Hello all
Problem/Justification
I am now for the first time expanding my RaidZ1 and I know it takes a long time. It is a bit scary that there is no progress indication or an estimate of time remaining.
I can see that it is in progress and an estimate of how long it will take for completion in the shell by using sudo zpool status.
Impact
It will be way less scary for especially users doing this for the first time.
It should be clearly visible, preferably on the dashboard that the expansion is in progress, how much time is remaining and that it will resume after a reboot.
User Story
Real story, I added a new hard drive to my raidz1 pool and began expansion. After about an hour or so, I remembered that my plan included adding a single drive for media that is not critical so losing it will be annoying, but not a big deal. so I did what any sane person would do and shut down my machine and added the extra drive.
when up again, I remembered that I was in the process of expanding my pool and was a bit worried that it didn’t work, but everything showed that all 4 disks (3 old and the freshly added) were fine, only the capacity was shown as what it was before I added the new drive.
I dug around the internet an found the “zpool status” command.
Thanks Sune
