Replaced HD in Zpool: Lots of disk activity before I issue the replace command
Posted: 17 Dec 2016 08:44
I'm hoping that this is an occasion where zfs is just getting on with the task rather than waiting for me.
The server is running the current release 10 of NAS4Free.
I had a HD fail in a 10 disk zfs2. No worries, its been running since 2011. I removed the drive with a new, unused drive of the same capacity. On restarting the server there is a lot of disk activity which indicates that the new disk is being re-silvered. However the information page doesn't report that re-silvering is ongoing.
Issuing a zpool status command from the console also does not report any re-silvering activity. I get the same report as above.
I'm hoping that something good is happening. But it does seem strange that there are no reports of what the activity is.
The I/O activity of the array is below.
Would anyone else be knowledgeable enough to pint me to where else I might be looking to see what is happening.
