Hi there,
In order to increase the size of my pool I started replacing and resilvering drives.
My pool is a 4 disk raidz2 with WD30EFRX disks that I am now replacing with WD50EFRX disks.
The replace and resilver of the first disk took about 10 hours. The resilver of the second disk is now running for 12 hours and just finished 50%, so it is considerably slower. It started with comparable speed for the first hour then went down.
Should I be worried? Could this be just normal?
I have stopped all services (AFP, NFS, CIFS) before starting. Also did a scrub before. SMART is not showing errors, messages neither.
The pool has a capacity of 86% which isn't recommended, I know, therefore going to increase size.
Freenas is latest version (FreeNAS-9.3-STABLE-201501090144) with updates applied.
Disks are attached to an IT flashed IBM ServeRaid M1015.
Disks have been hot swapped.
System is running with this configuration now for about 6 months without any issues so far.
Here is the output of zpool status:
