July 16, 20232 yr Guys, i've got a 16TB drive in my array and want to swap it for an 18TB, already precleared and tested. Is it just a simple removal of the smaller and swap in the larger after which that drive will be rebuild itself from parity? I think thats the way to do it but ist been a while and i have this worry that the drive will only be rebuilt to a maximum of 16TB ie the original sie of the removed drive? Or will i have at the end of the rebuild a rebuilt drive with an extra 2TB of available space? I've not touched Unraid for ages!! Thanks.
July 16, 20232 yr Community Expert Solution I’m assuming your parity drive(s) are at least 18TB as no data drive can be larger than the smallest parity drive? when you rebuild to a larger drive the last step is to expand the file system to fill the drive.
July 16, 20232 yr Author Yes, dual 18TB parity. Its that last bit confirming that filestore IS expanded that i was doubtful about. In the past i'm sure that i ended up with a 'like for like' copy of the smaller drive but on a larger drive and then needed to do some jiggery pokery to sort that out. Anyways thanks for confirming!

I seem to remember reading somewhere that it took a reboot to get the extra space made available but no more than that. Not tested it myself recently to be sure.
July 29, 20232 yr Author Well, we'll see soon hopefully. I pulled a 12TB drive and have replaced it with an 18TB. Expected rebuild time showed as 3days 5hrs'ish so away it went. 2 days into the rebuild the system rebooted (why??) overnight and i've had to restart it. On this second attempt i'm again 2 days into it, due to finish lunchtime tomorrow. Let's see what happens eh. The electric bill will be taking the hit again!
July 29, 20232 yr Community Expert You might want to try enabling the syslog server so we can get a syslog that survives a reboot. Posting your current diagnostics might allow us to see if you got an unclean shutdown or not. If you did not then this would suggest something actively shutdown your server.
