Bedey Posted November 19, 2019 Share Posted November 19, 2019 So, some days ago i replaced one failed disk with another similiar one, after the rebuild it give me this error "Unmountable: No file System", so after looking in this forum i ended with repairing the filesystem and all started to work as usual, but today i decided to upgrade another disk (still 3tb, like the parity one), and as the last time the new disk gave me the same error "Unmountable: No file System", but the real issue is that the other drive that i replaced some days ago give me another error "Unmountable: Unsupported partition layout" Is this correlated? can someone explain me what's happening? thanks Quote Link to comment
unw1red Posted November 19, 2019 Share Posted November 19, 2019 What procedure did you use to upgrade the disk? Did you use the data rebuild procedure? Did you preclear the disks? Quote Link to comment
Bedey Posted November 19, 2019 Author Share Posted November 19, 2019 Never precleared, the first time I just replaced a failed drive and waited for the rebuild, this time I just replaced a small disk but it can't be rebuilt because of the other drive/disk giving an error, right now I installed back the old small drive because it was working nicely Quote Link to comment
JorgeB Posted November 19, 2019 Share Posted November 19, 2019 Unmountable disk after upgrade would point to invalid parity, or errors during the rebuild, do you still have any diags from that? Quote Link to comment
Bedey Posted November 19, 2019 Author Share Posted November 19, 2019 Old parity and rebuild are error free, right now I'm restarting my nas(it takes a lot of time, I never solved that issue), I want to see if with old drives the array can be started Quote Link to comment
JorgeB Posted November 19, 2019 Share Posted November 19, 2019 Do you run regular parity checks? Quote Link to comment
Bedey Posted November 19, 2019 Author Share Posted November 19, 2019 Yes, pretty much every week My nas finally started up, but unfortunately it says I can't install a smaller replacement disk. So I'll write a summary Day one: replaced one disk, rebuild it and fixed file system, everything seems working fine Day three :upgraded one disk, turned on the system and the new disk give me this error "Unmountable: No file System" (I still didn't do a 2nd rebuild) and for no reason the disk I replaced the first day give me another error "Unmountable: Unsupported partition layout" and now after I put back the drive I replaced on the third day it says it's too small and can't be used So I'm screwed?

JorgeB Posted November 19, 2019 Share Posted November 19, 2019 You need to post diags after a rebuild and before rebooting when you do the next upgrade. Parity check every week is over kill, once a month is fine. Quote Link to comment
Bedey Posted November 19, 2019 Author Share Posted November 19, 2019 This is my situation Disk 2 is the drive i repaced the first day the other one should be the disk i tried to upgrade So first of all thanks for your help, i can't understand what i have to do Quote Link to comment
JorgeB Posted November 19, 2019 Share Posted November 19, 2019 Post current diags. Quote Link to comment

JorgeB Posted November 19, 2019 Share Posted November 19, 2019 Tools -> Diagnostics Quote Link to comment
Bedey Posted November 19, 2019 Author Share Posted November 19, 2019 Ok, should be this one petere-diagnostics-20191119-1846.zip Quote Link to comment
JorgeB Posted November 19, 2019 Share Posted November 19, 2019 Check filesystem on both disks, but this isn't normal, something else is going on, likely hardware related. Quote Link to comment
Bedey Posted November 19, 2019 Author Share Posted November 19, 2019 Ok I'll check asap, I hope is not hardware related, both of that drives are connected at the motherboard Quote Link to comment
Bedey Posted November 19, 2019 Author Share Posted November 19, 2019 Phase 1 - find and verify superblock... bad primary superblock - bad magic number !!! attempting to find secondary superblock... .found candidate secondary superblock... verified secondary superblock... would write modified primary superblock Primary superblock would have been modified. Cannot proceed further in no_modify mode. Exiting now. Result of disk 2 after i run a check with the command -n Quote Link to comment
JorgeB Posted November 19, 2019 Share Posted November 19, 2019 You need to remove -n (no modify) or nothing will be done. Quote Link to comment
Bedey Posted November 19, 2019 Author Share Posted November 19, 2019 tried with -L, seems kinda working, but inside the drive almost everything is missing and being replaced with "Lost+found" folder, guess i lost some data Quote Link to comment
Bedey Posted November 19, 2019 Author Share Posted November 19, 2019 I'm stuck, I can't assign my old 1tb drive to the 3rd disk, if I install a new drive I think parity with that the other corrupted drive will result in a total loss of all data Quote Link to comment
JorgeB Posted November 19, 2019 Share Posted November 19, 2019 14 minutes ago, Bedey said: I can't assign my old 1tb drive to the 3rd disk To do that you need to do a new config. 1 Quote Link to comment
Bedey Posted November 19, 2019 Author Share Posted November 19, 2019 I can do that without loosing any data? Quote Link to comment
JorgeB Posted November 19, 2019 Share Posted November 19, 2019 You'd lose any data on the emulated disk3 that doesn't exist on old disk3, i.e., any new data written after the replacement, all the other data will remain as it was, just make sure to assign old parity disk to the parity slot. 1 Quote Link to comment
Bedey Posted November 19, 2019 Author Share Posted November 19, 2019 I'll try right now Quote Link to comment
Bedey Posted November 19, 2019 Author Share Posted November 19, 2019 Well, array is on, how I should procede? Disk 2 data seems unavailable, can be rebuilded? Quote Link to comment
Bedey Posted November 19, 2019 Author Share Posted November 19, 2019 I checked pretty much every folder on disk 2, some stuff is still there, some seems lost forever, well better than nothing, but I still have to replace that old 1tb drive with my new 3tb one, how I'm supposed to proceed? Last time everything went badly and I just followed the wiki Quote Link to comment
