June 7, 20233 yr Hi everyone, I have upgraded to a new build yesterday (changed everything but the HDDs and Unraid's USB) and it seems to be working fine. That said, one of the disks was previously connected to the old pc via USB (it had a drive enclosure) and now it's directly plugged through SATA. That said, in the "Main" menu, the drive has changed ID. It still shows as a 12TB drive but it has a different name. This drive was previously part of a 4 hdd array. How should I proceed? Thank you!
June 7, 20233 yr Community Expert That's normal with USB, most time you just nee do do a new config, was the disk part the the array or a pool? Also please post current diagnostics.
June 7, 20233 yr Author Thanks! I didn't know that... The disk was part of the array! (I'm downloading the diagnostics as we speak... )
June 7, 20233 yr Author Okay, here's the diagnostics! 1 hour ago, JorgeB said: That's normal with USB, most time you just nee do do a new config, was the disk part the the array or a pool? Also please post current diagnostics. By new config... could you be more specific, JorgeB? I'm under the impression that with a new config I would lose data... About the HDD in question: it's a data HDD, part of the array. This array is pretty small and has no parity drive (it has a cache SSD though) How do you think I should proceed? As per Unraid's documentation and some community posts, I get the impression I can rebuild the array using the "new config" tool, which is non-destructible... but could you confirm me this information and help me configuring the tool? This HDD has lots of family stuff I'd rather not lose😅 Thank you in advance! tower-diagnostics-20230607-1623.zip Edited June 7, 20233 yr by fmmsf
June 7, 20233 yr Community Expert Solution Tools -> New config then re-assign the disks to the correct positions, according to diags there's no parity, so then just start array. Note that some USB enclosures change other things in addition to the ID, if that is the case the disk might not mount, if that happens post new diags.
June 7, 20233 yr Author I should proceed like this? There's a dialogue screen after this where I can re-assign the disks WITHOUT data loss? Edited June 7, 20233 yr by fmmsf
April 2, 20251 yr Sorry to resurrect this old thread, but It felt applicable. I currently have the issue, that I temporarily removed my HDD from the parity slot. Now ( I think due to the HDD bay being connected via USB) it is not getting the serial number of the hard drive correctly. Now I'm obviously scared that I will have data loss there. The currently selected HDD in my Parity Slot is the exact same drive, that was my parity before. Can I fix that by creating a new config as well? I DO have a failed HDD, that I have to return, but don't have the replacement yet (it was on disk 2). Should I wait until I have the replacement disk? Edited April 2, 20251 yr by shentoza

April 2, 20251 yr Community Expert New Config will keep you from rebuilding the failed disk. There is a way but you need the replacement disk to do it.
April 2, 20251 yr Community Expert In what way did the disk fail? Disconnect that disables a disk is another reason USB not recommended
April 2, 20251 yr Yeah, now I read that as well. But I didnt think I have an option to put another controller with my pc without putting cables out of the case https://psref.lenovo.com/syspool/Sys/PDF/ThinkCentre/ThinkCentre_M910_Tiny/ThinkCentre_M910_Tiny_Spec.pdf?clickid=zKu2mFTzGxyKUIh0tG0fhXFyUksyVfVDlQjg1w0&Program=3786&pid=242189&acid=ww%3Aaffiliate%3A74clty&cid=de%3Aaffiliate%3Axg02ds jarvis-diagnostics-20250402-1844.zip

April 2, 20251 yr Community Expert Note that some USB enclosures are not transparent, meaning the disk won't show the same info without it, also looks like you only had one data disk? If yes, parity is a mirror.
April 2, 20251 yr 12 minutes ago, JorgeB said: Note that some USB enclosures are not transparent, meaning the disk won't show the same info without it I dont think i quite understand the transparency bit... I took the screenshot, when i already removed the faulty disk. Yeah i had only one data disk
April 2, 20251 yr Community Expert 3 minutes ago, JorgeB said: See if parity mounts with the UD plugin. Unassigned Devices, you will have to install it.
April 2, 20251 yr ah since the parity drive is just a mirror of the one drive, just mount it into the old slot? But creating a new config should also work as well, right?
April 2, 20251 yr But where would it be mounted, though? I my replacement disk. I could use the new drive as parity disk then and just mount this one shown as data disk?
April 2, 20251 yr Community Expert The point in this case with UD is to see if it actually mounts and you can access its files. If not, there may be some more that needs to be done. Do you have another copy of anything important and irreplaceable?
