Is it normal for a FreeBSD system to freeze when a RAIDZ2 HDD disk errors?
I have a 11.2-RELEASE-p5 system running 2 pools.
ZPOOL - Mirror - 2 SSD's: Boot and root partitions
DPOOL - RAIDZ2 - 6 WD Red HDD: Personal data
Within the DPOOL I have had a spate of disks failing over the last few years. Initially I see CDB errors in the log pertaining to a particular disk. Then the system will start to freeze. It will respond to pings but not SSH. Upon reboot everything is fine. The ZFS pools are fine. Then it will freeze with increasing regularity. No indications in the log at the time of the freeze.
When I replace the disk from the DPOOL that was logging the CDB errors, the freeze goes away - until another disk is failing. (I think I got a bad batch of WD Reds - they last about 2 years.)
So, is it normal for a WD Red NAS drive in a RAIDZ2 pool to be able to hang a system??? I assumed that the RED NAS would time out and the ZFS system would flag the error and continue operating?
