If you need more advanced functionality than mpsutil provides, LSI provides their native tools sas2ircu and sas3ircu for FreeBSD. On my system, this command produces a bright red LED lit for that slot, physically highlighting the correct drive to replace. So, to activate the LED for the first disk displayed above, we first need to determine the enclosure handle number (0001), and then the slot number of the disk (03). This partitions each disk and labels the ZFS partition with the enclosure, slot, and serial number of the corresponding disk. As with a number of tools in FreeBSD, sesutil supports outputting JSON via the libxo library.
- I’m looking for a software solution, if possible, to make the HDD idling for most of the time when there is no load.
- FreeBSD’s sesutil is a tool to interface with the SES devices on your system.
- This example creates a new GPT partition scheme on da36, creates a 4 GiB swap partition aligned to 1 MiB boundaries, and then adds a ZFS partition with the label e3s01-ZGY0XH87 using the remainder of the space on the disk.
- When building a storage system, there are many different ways the disks might be connected to the system.
- The smartmon_load_cycle_count_value metric seems like it would be the right one to query, but that actually expresses a percentage value (0-100) representing how many load cycles remain in the specified lifetime- on reaching 0 the disk has done a very large number of load cycles.
- For smaller numbers of drives, and for most home systems, the most common way the disks are attached is to the SATA controllers built into the motherboard.
I set power mode to Idle and advanced power management to the lowest setting (1) which should spin down the disk after 5 mins. Hello,Like many users of Seagate Exos drives, I have found that they park their heads very aggressively, approximately every 2 minutes. AnyDesk allows you to establish remote desktop connections between devices and opens up unprecedented possibilities of collaborating online and administrating your IT network. Its primary purpose is to grant bidirectional remote access between personal computers and mobile devices. To do this, both devices must have the program installed and must allow access through the use of security keys. The current settings for a disk can be queried with the –showEPCSettings flag.

The APM specification dating from 1992 includes some controls for hard drives, allowing a host system to specify the desired performance level of a disk and whether standby is permitted by sending commands to a disk. In addition to the above query types, SES also supports a number of commands, including activating the “locate” and “fault” LEDs if present, and the ability to individually power off drives. The first step is to map out the relationship between the physical chassis where the disks reside, and the logical devices enumerated by the operating system.
In this case, there are at least two disks that I probably need to configure, since /dev/sde seems to be parking as often as about every 4 minutes (0.004 Hz) and /dev/sdc is only parking slightly less often. The smartmon_load_cycle_count_value metric seems like it would be the right one to query, but that actually expresses a percentage value (0-100) representing how many load cycles remain in the specified lifetime- on reaching 0 the disk has done a very large number of load cycles. It does support reading arbitrary metrics from text files written by other programs with its textfile collector however, which is fairly easy to integrate with arbitrary other tools. These communities are filled with knowledgeable individuals who can offer more personalized advice and help you navigate the complexities of long-term data storage.
SATA disks plugged directly into the motherboard use an interface called AHCI which does not provide much in the way of advanced management features. For smaller numbers of drives, and for most home systems, the most common way the disks are attached is to the SATA controllers built into the motherboard. Non-Volatile Memory Express (NVMe) is a newer storage interface that is becoming very popular for flash storage devices. Just download the executable file on both devices and run it to open the tool. At a glance, changing idle3 and EPC settings seems to have done the job nicely; here is the same graph of head park rates per disk as before, but on a smaller timescale that makes individual head parks visible. Seagate provide a “Seachest” collection of tools for manipulating their drives, but rather more usefully to users of non-Windows operating systems like Linux they also offer an open-source openSeaChest.
However, I noticed that my HDD’s heads park (particulary Seagate Exos) every 3 minutes. ZFS is widely trusted for large-scale storage, but production environments expose design mistakes,… When dealing with critical data, you only get one chance to do it right. The status field is a bitmask supporting a number of different options, but the main ones we care about are 1 (OK), and 2 (FAULTED). When combined with a JSON parser like jq, this can be used to automate tasks for each disk.
When it comes to long-term data storage, there are several strategies and media types that Redditors recommend. It refreshes the disks SMART information every 5 min. ZFS and Btrfs both aim to modernize storage by combining filesystems and volume management, but… Monitoring and maintaining your storage media is one of the most important parts of keeping your data safe.
Whether you are a computer technician in charge of technical support or a student who needs to work together with their classmates, AnyDesk is the program you are looking for. Then, click on “Connect” to access the other device. Send it to the other user who has the program and they will be able to access and control your device. It is very popular among professionals who provide technical support. Remember, the key is to act quickly and use the right tools for your specific situation. These practices and tools should give you a solid starting point for recovering your deleted files.
Labeling with GUID Partition Table (GPT)
- Its primary purpose is to grant bidirectional remote access between personal computers and mobile devices.
- Of particular note, WD Green drives ship configured to park the heads after only 8 seconds of inactivity which could notionally wear out the disk in a matter of months if the heads are cycling more-or-less continuously!
- Simply installing the apps and choosing a pool for k3s and docker creates a dataset and logs.
- Unnamed devices can be specified by their specific SES device and element number.
- SAS disk reservations provide the ability to connect to the disk redundantly—or even across multiple machines—while ensuring it is only used by one of them at a time.
SAS disk reservations provide the ability to connect to the disk redundantly—or even across multiple machines—while ensuring it is only used by one of them at a time. SAS provides many more features than SATA does—including full duplex operations, advanced error recovery, multipath, and disk reservations. It too was an extension on an existing interface bus which offered greatly improved performance. SATA+AHCI improved data transfer speeds, simplicity of communication, and included abilities that we today take for granted, such as “hot swap” and command queueing. These concepts also apply to other operating systems, but the tools might differ slightly.
Recommended Recovery Tools
I will optimize settings later for the security/quietness tradeoff however, I’m very pleased with it for now. How can I set this value on the Truenas interface? Keeping it spinning but not accessing data is safer. I would still recommend against idling your drive as that reduces longevity. I also set the tunable vfs.zfs.txg.timeout to a somewhat large value so the regular syncs don’t happen every 5 seconds.
AnyDesk for Windows
I moved my Scale server into the next room, laundry room, just so it’s out of sight. Replacing the drive is reveryplay financially out of the question. I’m looking for a software solution, if possible, to make the HDD idling for most of the time when there is no load. Yeah, it’s not helping, thanks. Although it’s empty, so this is probably not the source of the constant HDD noise.
Connect to a computer or mobile device remotely, whether it’s across town or halfway around the world.
I moved the system dataset to the boot pool. I don’t move any data, no apps are running, this is a vanilla Scale install so far, yet the HDD is in constant work. 1 SSD to boot and 1 HDD to store data. Agree, I have used SeaChest with good results for this same issue on scale plus drive cache. If you do it on a live pool, I’d back up your data first.
For chassis with larger numbers of drives, or when connecting external JBOD chassis, it is common for the drives to connect to a specialized board that provides power and routing for the SATA/SAS signals to the controller. When building a storage system, there are many different ways the disks might be connected to the system. NVME-oF allows storage devices and arrays in remote chassis to be connected to local motherboards. NVMe storage comes in many form factors, from small M.2 devices to U.2 and other hot-swappable formats intended for servers. NVMe connects storage devices directly to the PCIe bus, offering extremely low latency and high throughput.
The timer values specified are in milliseconds, so this example will park the disk heads after 30 minutes of inactivity. If we wanted to allow the disk to still park its heads but at minimum frequency, setting the APM value to 7Fh (hdparm -B 127) seems to be the correct choice. Of the three disks that I decided need some attention, I have one Western Digital disk and two Seagate ones.
I agree to receive your newsletters and accept the data privacy statement. Ensure device health & easy replacements with these valuable tips. Discover strategies to manage disk arrays on FreeBSD and related platforms/operating systems. Simply installing the apps and choosing a pool for k3s and docker creates a dataset and logs. Your pool gets writes from somewhere and ZFS is writing those to disk every 5 seconds.
Unnamed devices can be specified by their specific SES device and element number. This greatly reduces the chance of getting it wrong when you (or the datacenter technician) physically pulls the disk. You can also reboot, and GEOM will pick up the multipath when it first tastes the disks during boot.
Once you’ve done so, you must test delivery to your “real” inbox—you don’t want to learn that delivery isn’t working after your storage has already become unavailable! If you’d feel safer with a team of experts monitoring your storage, consider a ZFS Support Subscription. If you rely on manually checking on your storage periodically, you will regret it. Another important aspect of managing your storage system is configuring notifications. Klara recommends embedding these details directly into the ZFS vdev properties of each disk—a feature Klara created, which will become generally available in the upcoming OpenZFS 2.2 release. In these configurations, your system may or may not support features like individual “locate” and “fault” LEDs.
