Pool slow reads with normal speed writes

[iagocanalejas]

I have a dataset with 5x18TB drives in RaidZ2 that was working fine until a system reboot a couple of days ago. Now i can't manage to read from it.

• I have a SMB share to acces it, i can copy files at about 80MiB/s (same as before) and i can see all the files in the system but trying to copy files from the NAS to my local system fails.
• Trying with SCP i can also copy into the NAS, but trying to copy to my local system the speed jump from 20MiB/s to 1KiB/s and even 0 taking hours to copy a single 8GB file.
• Trying to rsync the files to another dataset runs slow (48days for 7TB)
• Iperf shows the network is not the problem as it shows the correct output both ways.
• I ran a couple of fio tests attached below

Code:

[Ericloewe]

Please, for the love of Cthulhu, don't use spoiler tags for console output, use CODE tags.

Also, what disks are these?

 

[iagocanalejas]

Sorry, first time using the forum, i have:

• 4x Seagate Exos X20 18TB
• 1x Seagate Exos X18 18TB

 

[Ericloewe]

So, not SMR. How does the SMART data look for these disks, any big red lights?

 

[iagocanalejas]

No errors were thrown in the GUI and everything was working fine until a system reboot, i have short and long smart tasks configured but i don't know how to see the logs for them.

 

[Ericloewe]

You can read out SMART data with smartctl -x /dev/sda (adjust accordingly for other disks)

Well, there are no immediate indicators of trouble there, but the disks aren't running regular SMART Tests. You should configure those. Most people run a daily short test plus two long tests per month.

 

[iagocanalejas]

I will try manually running long tests for each drive and see what happens. It will take a while.

 

[Ericloewe]

That's fine, but scheduled SMART tests are an important part of monitoring disk health (which can naturally impact performance)

 

[iagocanalejas]

Hi again, i finally managed to run all the long tests and all the disks are working fine, but my problem still remains, i can copy at normal speeds into the disks but i cannot copy out of them neither watch any of the video files on it it stops transfering after 3 seconds.

 

[iagocanalejas]

More information as i am doing more tests, if i power off any pair of disks (it's a RAIDZ2 so it can work with 2 drive "failures") it works fine. But when i power the drives on again it returns to the same error.
