January 6, 201610 yr What's the expected behavior of a cache drive failing while the array is online? In the event of a cache drive failure, will UnRAID simply skip the cache drive on the next file and continue to write data to the array without much of a hickup? Or is this a catastrophic system halt that requires manual intervention to fix and bring the system back online? Anyone experience this?
April 13, 201610 yr I am wondering the same thing. Just got another unraid pro key backing up and going to try some break testing soon with 6 drive raid 10 cache Sent from my SM-N910W8 using Tapatalk
April 13, 201610 yr I think the answer to this question is... it depends on the nature of the failure.

I think the answer to this question is... it depends on the nature of the failure. From looking at various syslogs, it appears that if the cache drive (and its the only one) drops offline, then while it's not catastrophic per se, the entire share system goes down, and at the very least a stop / start of the array or a reboot will be necessary to restore the system to functional status. But, read or write errors to the cache drive should not affect the share system, and unRaid will continue on its merry way with errors in the syslog and/or errors popping up in Windows, etc depending upon what was going on.
