Hi all,
Before we start, hereby the system I am running:
- Intel I7
- 4x 4GB RAM
- Asrock-z77-extreme4 motherboard
- 240GB SSD (NEW)
- 4x 2TB HDD (NEW)
ESXi 6.7 is running on a 32GB USB-stick and FreeNAS 11.2-stable is installed on the 240GB SSD. I got the 4x 2TB HDD connected to FreeNAS with a pass-through workaround: https://gist.github.com/Hengjie/1520114890bebe8f805d337af4b3a064 . This does work all fine and I see the HDD's in FreeNAS.
The 4 HDD's are in a ZFS-pool RAIDZ.
I have a problem with FreeNAS running on ESXi. FreeNAS keeps giving the message: "Device: /dev/da1, 8 currently unreadable (pending) sectors". It started with the number 8 and is now at 56 over a couple of days. Today it also stared giving the message for /dev/da1 (8).
My first reaction was to check the HDD's for badsectors. I did this on FreeNAS layer with the commands "badblocks". Did this for all 4 HDD's. On one it gave back that there were 16 badblocks, i manually checked them and i could read them out correctly, so it looks like this was a false-positive.
Conclusion; it looks like that the HDD's are all fine, but FreeNAS keeps giving the message that there are unreadable sectors...
Can you guys help me to troubleshoot this and hopefully fix the problem!
