cache unused
Posted: Sun Jul 06, 2014 10:05 am
I have a pool with a 32G cache defined. after reboot it slowly fills up and is used according to "iostat -v". If i export that pool and then import it back, the cache never gets used again. After reboot, the caches is used again.
Any init that happens ager reboot but not after import?
cheers
Currently it looks like below. I rebooted 1hrs ago and the cache is slooowly filling up.
After export/import the last line would look like:
