Hi,

I've got a RAID array, which is made up of 4x3TB drives, set up as a RAID 5 array.

I'm getting errors in the log, basically telling me that drive 1 may be on the way out. I checked because the transfer speed dropped like a stone, and I was having trouble streaming videos.

My question is, since I have to replace the drive, if I put in a 4TB drive then replace the rest of the 3TB drives, one at a time, as funds permit, with 4TB drives, will the array magically rebuild itself to use the full space available, once all of the drives have been swapped?

Or will I have to back up my data then manually build a new array?

Thanks in advance.

:)

Edit to add: I did gracefully shut down unit before I went to work, on the off-chance that it's just pissed off about something and turning it off and on again might help. I doubt it will, but it's worth a shot...

If you add a 4TB then it'll rebuild using 3TB of that disk.

If it's in XRAID then you can only expand once you've replaced all the disks with larger drives (one at a time & let it rebuild each time

Thanks for the quick reply! I'm 99% certain that it is XRAID, but I won't be 100% until I get home.

Now all I need to do is source some drives. Silly question, but I'm guessing that I should be looking for NAS HDDs, since it is left on 24/7?

I'd certainly go for NAS specific drives if you can. They are designed to deal with the vibration you get in multi-drive setups better than regular drives.

WD Reds are always good. Or anything enterprise.

Drive received and replaced. According to the admin' page, there are only 41 hours left to resync.
