Hey everyone,
at first, here my FreeNAS Configuration:
- RaidZ2, encrypted
- 7 4TB HDD (Seagate Desktop), to be replaced by 7 8TB IronWolf (Standard, not Pro)
- Supermicro X9SCL-F
- Xeon E3 1220V2
- IBM M1015 Raid-Controller, flashed for IT Mode
- 32GB ECC Ram
- FreeNAS-11.1-U1
Now the problem:
I wanted to increase the size of my RAIDZ2 Dataset, by changing drive by drive by a bigger one.
For this reason, i followed the guideline in the FreeNAS Documentation, unfortunately (my silliness), i thought i have no time and a RaidZ2 Configuration, I set 2 4TB drives offline and replace them by the Seagate IronWolf 8TB.
Everything so far went fine and it was resilvering already for about 4 Days to ~80%. Then, without any warning, FreeNAS rebooted and i had to start the resilvering process again (it started around 40% progress, for whatever reason) and at ~ 55% FreeNAS crashed again and rebooted.
Consequently resilvering started again by itself, but this time at 0%. The first 20% were very fast (around 4 hours), the next 5% already now needed 8 Hours. CPU is almost idle, same for the HDDs.
What is best way, to solve this problem? Can I get somewhere logs, where I will find, why it crashed and why it becomes so slow?
Is it smart, to remove one of the 2 8TB Seagate Drives, to resilver at first only one pool?
On the screenshot is the zpool status to see, with its current progress. Until now I had NEVER a problem with any of the HDDs, as well as with unstable FreeNAS System (everything worked always perfectly fine).
Thanks already for your help.
