Unfortunately, APM settings don’t persist between power cycles so if we wanted to change disk settings with APM they would need to be reapplied on every boot. Advanced power management levels80h and higher do not permit the device to spin down to save power. For example, a device may implement one power management method from 80h to A0h and a higherperformance, higher power consumption method from level A1h to FEh. To prevent parking more often that is useful (for a server, usually that choice would be “very rarely”), there are a couple ways to do it and which apply will depend on what the hard drive vendor’s firmware supports. With the SMART metrics captured by Prometheus, it’s fairly easy to write a query that will show how often a given disk is parking its heads. Since I use Prometheus to capture information on the server’s operation however, I can use that to monitor that my hard drives are doing well.
Verifying settings
At somewhat larger scales, a number of drives can be connected directly to a SAS (or SATA) controller PCIe card. But, if the number of ports on the motherboard is sufficient to your needs, this is the easiest way to connect the drives to the system. We are going to focus on some of the most popular for SATA and SAS drives.How do I accept a connection request with AnyDesk?
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. 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. 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.AnyDesk for Windows
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. 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). Below we will discuss exactly how to do this with FreeBSD’s sesutil or the management tools for your HBA. Though a truism, it bears emphasizing that with a little planning, management and maintenance of storage systems can be made easier and safer. The total throughput possible from the connected disks is still limited by the number of lanes available, but this is likely the best approach in systems with more than a dozen disks.How to Convert a Recorded AnyDesk Session in 3 Easy Steps
It’s hard to imagine why your drives are that loud! It’s a datacenter drive, very loud, so it’s still audible. For quietness, a noise reducing case, move it somewhere else, quieter drives, maybe SSD instead of hard drives, etc.- Unfortunately, APM settings don’t persist between power cycles so if we wanted to change disk settings with APM they would need to be reapplied on every boot.
- On my system, this command produces a bright red LED lit for that slot, physically highlighting the correct drive to replace.
- Monitoring and maintaining your storage media is one of the most important parts of keeping your data safe.
- NVME-oF allows storage devices and arrays in remote chassis to be connected to local motherboards.
- Your pool gets writes from somewhere and ZFS is writing those to disk every 5 seconds.
- Below we will discuss exactly how to do this with FreeBSD’s sesutil or the management tools for your HBA.
- 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.
Constant HDD noise -> how to stop it?
- It’s a datacenter drive, very loud, so it’s still audible.
- Although it’s empty, so this is probably not the source of the constant HDD noise.
- Send it to the other user who has the program and they will be able to access and control your device.
- 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.
- SAS provides many more features than SATA does—including full duplex operations, advanced error recovery, multipath, and disk reservations.
- 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.
