Using the no-op true command on other paths to that disk, will cause GEOM to re-”taste” the disk and see the label and automatically add the additional paths to the existing multipath. This will write a GEOM Multipath label to the last sector of the disk. Each SAS Expander will present as a new /dev/ses# device, so your system may have more than one.
We can also see that the disk in Slot07 was recently swapped, and that Slot08 does not contain a disk and its locate LED is activated. SES provides a mechanism to query information from the enclosure, including temperature, fan speed, and status of power supplies. Many backplanes include support for SCSI Enclosure Services (SES).
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.

Direct Attached deployments require a bit more hardware and cabling. The NVMe interface is also extensible to allow operating over the network (where it is known as NVMe Over Fabric or NVMe-oF). NVMe on the other hand, supports multiple queues (often 64 queues, but the official specification allows for up to 65,536 queues) allowing for many commands to be run concurrently. While both SATA and SAS allow multiple commands to be issued at once to the device, these commands cannot actually be executed concurrently—instead, they are queued for sequential operation.

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.
- It’s hard to imagine why your drives are that loud!
- The system is never idle really, it’s a server.
- It refreshes the disks SMART information every 5 min.
- NVMe on the other hand, supports multiple queues (often 64 queues, but the official specification allows for up to 65,536 queues) allowing for many commands to be run concurrently.
- At somewhat larger scales, a number of drives can be connected directly to a SAS (or SATA) controller PCIe card.
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.

The parking rate basically drops to zero at the time I updated the settings for the Seagate drives, and the Western Digital one hasn’t changed because it needs to be powered off to change that setting and I haven’t done so yet. The other slight annoyance when setting the idle3 timer on WD drives is that changes only take effect when the drive is powered on, usually meaning the host computer must be fully shut down and started back up for any changes to be seen- this makes experimentation to determine how raw timer values are interpreted a slower and more tedious process. 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! For drives made by Western Digital, the inactivity timer for parking the heads is called the idle3 timer.

- It’s self-hosted and self-managed, so data remains within your company network.Bank-Level EncryptionBanking-standard TLS 1.2 technology protects your computer from unauthorized access.
- Advanced power management levels80h and higher do not permit the device to spin down to save power.
- Disk vendors typically provide their own vendor-specific ways to do persistent configuration of power management settings, so it’s worth trying to use those instead so the desired configuration doesn’t depend on the host system applying it, instead being configured in the drive (but in some cases it might be desirable to have the host configure that!).

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 reveryplay storage media is one of the most important parts of keeping your data safe.
For ZFS users, automating fault responses with tools like ZED (ZFS Event Daemon) can simplify disk replacement and minimize downtime. Configuring your system to notify you when a disk has errors, or when the filesystem reports a degraded device, will ensure your system gets prompt attention when something goes wrong. Experienced enterprise storage managers also keep extensive notes including the model number, SKU and/or URL for reordering, purchase order information, warranty end date, warranty URL, and any other useful information about each drive. While the operating system typically provides device aliases based on the disk’s serial number, WWN, or some other static identifier, this does not provide all of the information you might want.

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.
Sounds like the drives being woken for the ZIL to flush writes to the ZFS pool and then going back to idle/sleep every 5 seconds. Enable the checkmark for the Syslog and choose a pool that is not based on hard drives. I had this same problem, using HGST data center refurb drives.
Understanding Storage Protocols
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.
Verifying settings
I moved my Scale server into the next room, laundry room, just so it’s out of sight. Replacing the drive is 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.
