Raid 5 Error

[Fionn]

Hi Team

Have some issues with raid as it seems its stuck on Configuring… 0%

Model F4-210
TOS version 4.2.31-2203011629

Following has been done:
Disk 1: SSD - for a small database. Has not been altered in any way. Single disk config
Disk 2: HDD 12TB with ~7,2TB used from 11TB available. Single disk config
Disk 3: Empty
Disk 4: Empty

In disk3+4 a 10TB HDD has been added and a raid 1 was created from 0. It took about a day to complete. Progress has been updated all the time. Was a somewhat heavy load for the NAS CPU (70-90% usage).
Rsync from the TOS Desktop has been used to copy all data from HDD 2 to the new raid. Took about 2 days (why was it this slow? this is like 40MB/sec transfer rate). Was a somewhat heavy load for the CPU as well as before.
Once all data has been copied a new share was added to the new raid. Works perfectly. All files available.
Disk 2 (12TB HDD) has been removed from the NAS physically.
A new 10TB disk has been added into Disk Slot 2
The raid 1 setup in slot 3+4 has been expanded to a raid 5 with the new disk.
As the old storage pool for the 12TB HDD is useless now it has been deleted after the volume has been removed.

This was done about 8 hrs ago but it looks like the progress bar is not updating properly and NAS CPU usage is worst case 5-10%

CPU usage 7.52%
CPU temperature 42 ℃
Disk temperature 41 ℃

If there would be a load on the CPU I would assume its doing something. What now? Thanks for the help.

You can log in to ssh and run the cat /proc/mdstat command to check whether the array is synchronizing. Perhaps a part of the disk is synchronizing slowly.

Thank you for the feedback.

Still unchanged, any ideas?

It seems that the deletion of storage pool 2 and volume 2 has not been completely completed. You can try again after restarting. If you still have problems, please contact the technical support team or the customer service window, and let the engineer help you adjust it.

Hi TMzethar

Thanks for the suggestion. I did a reboot.
Deleting the storage pool vanished, and the rebuild started

Will be complete in 4 days (waaaaaaaaay better than 599 years )

Thanks for the help, I think from now on it will be fine.

Thank you!

Completed fine, everything works as planned Thanks again.
