Rehnquist Posted May 2, 2021 Posted May 2, 2021 Hey all, I got lazy about keeping up with my NAS for a few years and powered it on to check if it still worked. I have a 12-disk array with 1 parity drive and I was greeted to 1 drive showing "not installed" and the rest are fine (I think) though another is showing as unformatted. -Can I check that the other drives are actually healthy when I cant start the array? -How do I figure out why disk1 is showing as unformatted? I don't think thats how it should be. -I ordered a new harddrive the same model as I was ordering previously, my understanding is I replace disk8 and it should try to rebuild the array with the other drives. Is that correct? What other steps should I be taking to get this back up and running? Thanks for the support! Quote

After you get things fixed you really need to upgrade. Difficult to support a release candidate from nearly 9 years ago. Nobody that helps on the forum has seen that version in a very long time.

Rehnquist Posted May 12, 2021 Author Posted May 12, 2021 (edited) Agreed, that's the plan! Hoping to get this up and running, back up what I need to, then start from the ground up. Attached is the SMART report, I selected the longer test and the page refreshed with this pretty quickly. Can you tell if the test failed and ended or if these results are incomplete and I need to wait a few hours for it to update? Smart Report.txt Edited May 12, 2021 by Rehnquist Quote
trurl Posted May 13, 2021 Posted May 13, 2021 That one is so bad it does make me concerned about your other disks though, since they will be needed to rebuild that one. So many things in V6 make it easier to keep up with this so you don't run it into the ground. Quote
trurl Posted May 13, 2021 Posted May 13, 2021 Do you have another copy of anything important and irreplaceable? Repairing filesystem on disk1 might be more important than replacing that other disk if you need to get any files off. Quote

JorgeB Posted May 13, 2021 Posted May 13, 2021 Best bet IMHO is to use ddrescue to clone disk1 to a new disk, then you can try to rebuild disk8 using the clone as disk1, there will likely be some or a lot of data corruption on the rebuilt disk, mostly depending on how successful ddrescue is, you can also run reiserfsck on the cloned disk1 before or after rebuilding, no point in trying to run it on the failing disk1, it will abort due to i/o errors.

Rehnquist Posted May 13, 2021 Author Posted May 13, 2021 So do I pull that drive and plug it (with one to clone it to) into another machine to run the ddrescue? Sounds like thats worth a shot at least Quote
JorgeB Posted May 13, 2021 Posted May 13, 2021 If you upgrade to Unraid v6 you can do it there, if not use another PC. Quote

I had assumed it was for the disabled disk. Might be useful to have SMART for each disk. V6 makes it very easy to get SMART for all attached disks and much other useful info in a single Diagnostics zip download. Glad I am not working with V5 anymore. What else can you tell us about your hardware? V6 requires 64bit CPU and at least 2GB RAM. Quote

Rehnquist Posted May 14, 2021 Author Posted May 14, 2021 Could I install unraid v6 on a new USB drive and try to boot up from that? Quote
JorgeB Posted May 14, 2021 Posted May 14, 2021 You can use the same flash drive, just backup current one first, you can also use a new one but will need to transfer the key. Quote
Rehnquist Posted May 22, 2021 Author Posted May 22, 2021 (edited) Whats the best way to backup a flash drive on unraid 5? Edited May 22, 2021 by Rehnquist Quote

I think on Unraid v5 the flash drive was automatically exposed as the 'flash' share so it can be done over the network. Best to do it with the array stopped so that you do not get an automatic parity check (due to an unclean shutdown) if you ever need to use it. Quote
Rehnquist Posted May 23, 2021 Author Posted May 23, 2021 I backed up the boot drive, how do I upgrade to v6 from v5? Quote
