Going to be a few more days i suspect 🙂 Quote Link to comment
itimpi Posted May 31, 2019 Share Posted May 31, 2019 /mnt/disks is where the Unassigned Devices plugin mounts devices. It should normally only show drives that are not assigned to the array. However you can also sometimes get a disk showing there if a drive temporarily drops offline and then comes back online with a different device id. Unraid does not support hot-swap so does not recognise the changed id refers to a drive that previously had a different id. Quote Link to comment
helpermonkey Posted May 31, 2019 Author Share Posted May 31, 2019 Okay so i obviously don't know what the fudge i'm doing still... so i loaded up MC navigated to the disks directory and the disk1 directory .... and went to copy by using F5 but it doesn't seem to do anything. I tested in another directory using F8 to delete and that worked like a chanp... what am i doing wrong? Quote Link to comment
JorgeB Posted May 31, 2019 Share Posted May 31, 2019 You need to open the ST2000XXXXX folder, but in some cases the function keys don't work correctly when using the built-in terminal, if that's the case use Putty. Quote Link to comment
helpermonkey Posted June 1, 2019 Author Share Posted June 1, 2019 So I SSH'd in and copied the directories ... when i came back to it finished the directory sizes don't match.... the drive on the left is the 2TB and ther drive on the right is the 8TB. Should I just delete the music and videos off the 8tb and try to recopy them? or is this good enough that when i put back in the parity drive and start the array that unraid will figure out what's missing from where?

( -n means dryrun, no any writing will perform ) From compare the size, only several hundred MB different. Edited June 1, 2019 by Benson Quote Link to comment

Vr2Io Posted June 1, 2019 Share Posted June 1, 2019 (edited) Could you type " ls /mnt/disks/ " 1H3164, not 1H1364 ... Edited June 1, 2019 by Benson Quote Link to comment

Vr2Io Posted June 1, 2019 Share Posted June 1, 2019 So that mean 94.41GB need to transfer for sync from UD to Disk1, if you OK just remove " -n " then it will do the sync. 94.41GB won't take much time. Quote Link to comment

Vr2Io Posted June 1, 2019 Share Posted June 1, 2019 (edited) OK But best and safe as below rsync -ah --stats --max-delete=200 --delete-before --force /mnt/disks/ST2000VN000-1H3164_W1H2RQHS/ /mnt/disk1/ Then you can excute again and again to confirm created / deleted / transferred was 0, that means sync done.

Okay - now i've gotta wait on my new sata card and then when I get everything else confirmed i'll post here before i restart the array just to make sure i've fixed all the problems. One other quick question - would it be advisable at some point to move the data on disk 3 (which is almost full) to disk 1 now that it is 8TB? If so - how would i go about doing that? Since I'd want to keep disk 3 in the array but just give it more space. Edited June 1, 2019 by helpermonkey Quote Link to comment

I will set left 100GB space on each disks, because the largest file was bluray ISO, so free this amount would enough and avoid no space error occurred during file placement.

Soooo ... i think i'm ready to fireup the server ... here's the status page... also - fyi - i've started getting more of those UDMA errors that I thought was cable/card connected ... johnnie helped me get that equipment swapped out - however, now i'm getting errors on ones that are connected directly to the mobo AND when they were in other locations, were not showing errors (nor were the drives in the existing slots showing errors). Is it possible this is just a symptom of all the changes going on? Is there a way to double check or test these things otherwise? Disk 1: 199 UDMA CRC error count 0x000a 200 200 000 Old age Always Never 3522 this is the new 8TB data drive. When i first inserted this drive, i was doing a preclear on both the parity drive and this drive at the same time. However, I realized (after reading) that these were problematic so i stopped the preclear on Drive 1 and then ran it alone and from the begining after that.... the errrors have always showed up. Disk 2: 199 UDMA CRC error count 0x0032 200 001 000 Old age Always Never 331 Disk 3: 199 UDMA CRC error count 0x0032 200 196 000 Old age Always Never 2567 Disk 5: 199 UDMA CRC error count 0x003e 200 199 000 Old age Always Never 8 (this is the one plugged into the new card with the new cables). So a) can i fire this up again and start the parity sync-data rebuild? b) what do i do about these errrors? Quote Link to comment
itimpi Posted June 10, 2019 Share Posted June 10, 2019 (edited) CRC errors never reset to zero. - they only accumulate. If you click on the orange icon on the dashboard then you can use the Acknowledge option and Unraid will then only tell you if the value changes. Occasional CRC errors are not a problem, but if they occur regularity they indicate a connection problem that is probably adversely affecting performance.

Cool! does it look like i'm good to go to start this thing back up again then? i'm assuming it won't lose any of my data after all the prep but just want to make sure.

Yep, double check parity is correctly assigned, as any data on the disk assigned as parity will be deleted, also if after array start any of the data disks comes up as unmountable, don't format, post diags.
