Planning Ahead for Capacity Upgrade
Well, the ol' 4TB based volume in my 516 is down below 3TB free space. FWIW, this somehow got created as a RAID-5 under X-RAID2, but with 4TB disks it wasn't so bad. After some thought and looking at...
The volume will only expand when redundant space can be added. So if you have one 12TB disk after the RAID-6 volume is rebuilt you will still have dual-redundancy.
After you've created the RAID-6 volume you can re-enable X-RAID.
In fact depending what disks are installed, with a RAID-5 volume with three or more disks you could disable X-RAID and designate it so that when the next empty slot is filled it is used to add parity (i.e. convert to RAID-6). This conversion does take a long time though.
Well, i've gotten into a bit of a pickle it seems. Was working on config for one of my installed apps, but it's service got stuck (zombied), so I used FrontView to reboot the NAS. The resync for the volume is at about 20% (after a couple days). System goes through normal reboot, and I see disks fire back up and all looks normal... except that /data appears gone. :(
So far what I can tell from madm is that the array is there and in State "clean, degraded, reshaping" and Reshape status is 22%. Strangely, I received the following messages from ROS:
02:01:27 Remove inactive volumes to use the disk. Disk ...
02:02:01 Remove inactive volumes to use the disk. Disk ...
02:02:20 Resyncing started for Volume data
02:06:00 Remove inactive volumes to use the disk. Disk ...
On the front panel, I see period display of "Reshape data ...%", but of course when I bring up the Vol display is says "data 0/0TB". In FrontView, the volume is red, but it also says "Resyncing in progress: ....% complete. Remaining time: 240+ hours". I'm paraphrasing some of the figures, just because they're changing.
So... it would certainly appear the DATA is there, but any thoughts on why it's reacting as if the /data volume isn't? What's the best course at this point? Do I simply have to expect /data to be unavailable until the reshape completes now? Or is there a way to get /data reconnected while that's in progress? And, if I do /nothing/, what happens when the reshape is completed? Does it just remount the volume and everyone's happy?
I suppose I could open a support ticket too, but since I've been tracking this here I thought I'd update.
