gideva Posted March 27, 2020 Share Posted March 27, 2020 Hi guys, got a disk failure and I decided to replace it with a new one. I pre-cleared it and than I begun the rebuilt process that started normally and with no problems. I went to sleep and the estimated finish was around 15 hrs but this morning I woke up and the estimated finish is now almost 300 days... On top I can see now some errors on a different disk that I am not sure were there yesterday night. Attached a diagnostics file that I just download if it is of any help. monstruo-diagnostics-20200327-0915.zip Quote Link to comment
JorgeB Posted March 27, 2020 Share Posted March 27, 2020 Disk8 dropped offline, looks more like a connection problem, cancel rebuild, replace cables on disk8 and try again. P.S. there were also a few read errors on disk19, and that looks like an actual disk problem, if it happens again the rebuilt disk can have some corruption. Quote Link to comment
gideva Posted March 27, 2020 Author Share Posted March 27, 2020 Thanks. Will do Quote Link to comment
gideva Posted March 27, 2020 Author Share Posted March 27, 2020 Ok Done... Now that I restarted the rebuilt the disk 8 say: Unmountable: no file system. Normal? Quote Link to comment
JorgeB Posted March 27, 2020 Share Posted March 27, 2020 Not normal, but also not that unexpected, post new diags. Quote Link to comment

JorgeB Posted March 27, 2020 Share Posted March 27, 2020 Unfortunately disk8 also appears to be failing, stop the rebuild and run an extended SMART test, take the opportunity and do the same for disks 10, 14 and 19. Quote Link to comment
gideva Posted March 27, 2020 Author Share Posted March 27, 2020 Doing it now... Quote Link to comment
gideva Posted March 28, 2020 Author Share Posted March 28, 2020 Ok... after almost 20 hrs the Extended self-test routine seems to be stucked at 90% (since several hours now...). According the Extended self-test routine recommended polling time it was supposed to be done in around 527minutes. What next? Sorry if I am useless but I already lost several disks in the past without being able to recover the data and now I would like to do things in the correct way. Quote Link to comment
JorgeB Posted March 28, 2020 Share Posted March 28, 2020 You should wait a few more hours, if the disk as slow sectors, and very likely there are some due to the very high number of raw_read_errors, it can take much longer than a healthy disk, SMART test should never get stuck, it either completes or aborts with an error.

gideva Posted March 28, 2020 Author Share Posted March 28, 2020 It just finished!!! It says Completed without error... Quote Link to comment
JorgeB Posted March 28, 2020 Share Posted March 28, 2020 Longer than normal time means disk might be marginal, but if there's no error it's OK for now, all other disks I mentioned above also finished without error? Quote Link to comment
gideva Posted March 28, 2020 Author Share Posted March 28, 2020 Did not know I could have done all together.... Sorry. Started all of them now. Shall I start again the Data Rebuilt? Or shall I wait all the disks to be checked? Quote Link to comment
JorgeB Posted March 28, 2020 Share Posted March 28, 2020 Best to wait for the other tests. Quote Link to comment
gideva Posted March 29, 2020 Author Share Posted March 29, 2020 Finally all checks are done (I attach the results of the three disks). They all return a Completed without error message even (I do not know how important it is) all three disks have Current Pending Sectors in yellow... I am waiting more instructions to follow! Thanks a lot for the help and the patience monstruo-smart-Disk8.zip monstruo-smart-Disk14.zip monstruo-smart-Disk19.zip Quote Link to comment
gideva Posted March 30, 2020 Author Share Posted March 30, 2020 Still same problem.... The estimated finish is oscillating between 295 days and 24 hours. Normal? Quote Link to comment
JorgeB Posted March 30, 2020 Share Posted March 30, 2020 As long as there are no read errors let it go on, some of your disks appear to be marginal (but OK for now), and when reading those slow sectors zones speeds can fluctuate a lot. Quote Link to comment
gideva Posted March 30, 2020 Author Share Posted March 30, 2020 Ok. So for the time I let it go till is done. Just wondering how long shall I set as maximum waiting time (2/3 days?). Shall I plan to change disks 8,14,19? Thanks Quote Link to comment
gideva Posted March 30, 2020 Author Share Posted March 30, 2020 Second thing... Can I copy files into the server even if the Data rebuilt is running or shall I wait when is completed? Quote Link to comment
JorgeB Posted March 30, 2020 Share Posted March 30, 2020 7 minutes ago, gideva said: Just wondering how long shall I set as maximum waiting time (2/3 days?). I would estimate max a couple of days, any more you'll likely get errors first. 8 minutes ago, gideva said: Shall I plan to change disks 8,14,19? I would, IMHO it's just a matter of time until they fail again. 5 minutes ago, gideva said: Second thing... Can I copy files into the server even if the Data rebuilt is running or shall I wait when is completed? You can, but it will slow down even more, so avoid as much as you can. Quote Link to comment
gideva Posted March 30, 2020 Author Share Posted March 30, 2020 Thanks a lot for the help. Will keep you posted on how it goes. Quote Link to comment
JorgeB Posted March 30, 2020 Share Posted March 30, 2020 Regarding the disks when this is over you can run the diskspeed docker, it might help identify which ones are performing worse. Quote Link to comment
gideva Posted March 30, 2020 Author Share Posted March 30, 2020 Ok. I surely will Quote Link to comment
