[Resolved] software raid resynchs too much

Post by ant2ne » 2018/12/20 19:57:56

I have an HP server with 40+TB linux software raid 6 with a hot spare. For the past week the server has been resyncing. It has done this at least 3 times that I’ve witnessed. It completes it just fine after several hours, but it will randomly begin to resynch again. I’ve disabled /etc/cron.d/raid-check so it isn’t cron kicking it off. Does anyone have any ideas what is causing this thing to continually resynch.

The reason for the resync may be recorded in /var/log/messages or in the output of dmesg.

it really isn't logging much of value. Nothing that tells me what happened.

How about posting the output here so we can see it too.

For anyone else who may encounter this problem. It was bad sectors on one of the drives kicking off the resync repeatedly. After replacing the bad drive it did 2 more resyncs (which made me nervous) but then stopped after that.
