How to force expansion in RAID-X after disk addition?
I have an RN31400 using X-RAID and the latest firmware (6.9.1). I had 4 disks, 8T8, 8Tb, 6Tb & 6Tb. I replaced the third disk with an 8Tb one, meaning I now have 8Tb, 8TB, 8Tb & 6Tb. All are WD ...
Sorry, 15.5Tb, not 14Tb of available space.
Did you start with all 6TB's? It sounds like it's only using 6TB on all of your drives. Is XRAID enabled? That would be the case for Flex-RAID.
Do ou have SSH enabled and can you go in and execute lsblk? That will show you what partitions on what drives are included in your volumes. Post results here if you need help interpreting them.
No, the two 8’s and the two 6’s. They weren’t XRAID, so converted to that first. That’s obviously where the problem occurred. Th question is, apart from a fresh reset again, can I force it to do XRAID properly?
I think I can SSH in, but what will that show me? Can I then use a command to fix it?
Thanks.
You should have had a 20 TB (~18 TiB) volume before you upgraded the disk.
Do you recall what RAID mode you were running before you switched to XRAID?
I uploaded my SSH oputput, but it seems to have disappeared!
The issue seems to be that there were multiple RAID arrays - I think it must have been in Flex-RAID format. I removed a disk and replaced it with a bigger one, but just as it was rebuilding it said there were several RAID. Once it had rebuilt I changed it to XRAID. I guess I should have done the conversion before removing the disk.
If there's no specific command to force expansion or somehow work out whixh RAIDs to remove, then I'm supposing the only option is a wipe and rebuild, which is a pain in the $#@#$, but I have a backup. Here goes my weekend....
