May 17, 201115 yr Sorry, another newbie needs saving from herself ! Enjoying Unraid V4.7 (syslog attached), and all was well, with 2x WD20EARS 2TB drives and another WD20EARS parity (plus cache), using a Gigabyte GA870A-UD3 mobo, Athlon X2 and 4Gb memory. I added another new WD20EARS which appeared as hda rather than sde, ran a recent preclear script with -A, which completed with no errors, and then set off the disk format. Wondering why the full preclear took so much longer than the other WD20EARS drives, I realised that I must be using IDE compatibility in the BIOS (the others were all AHCI, I guess). Rather than being patient, I cancelled the format after 10% through the main window, rebooted, set the drives to AHCI in the BIOS (the setting affected SATA 4 onwards, which is why the earlier drives were all sda thru sdd), rebooted, then noticed that UNRAID recognised the drive even though it wasn't fully formatted.... There didn't appear to be a way to format it again, so I ran a parity check which found about 100 sync errors. I've since run a reiserfsck on the drive which reported no errors. Interrupting the format was silly of me - is the drive in a state that I can safely write to it? Is everything ok, or should I reformat the drive - if so, how? (The serial no. of the new drive ends 4707 in the log) Many thanks, Judy syslog.zip
May 17, 201115 yr Author Thank you Joe. Could you please point me to where I can do this - it's no longer possible to do this from the 'Main' page? JUdy
May 18, 201115 yr Thank you Joe. Could you please point me to where I can do this - it's no longer possible to do this from the 'Main' page? JUdy I think you'll need to do it on the command line. You'll need to do it with the array running. You'll need to un-mount the file-system umount /dev/diskX Using the correct disk for disk1, disk2, disk3, etc. Let's assume it is disk2. The command would then be: umount /dev/disk2 then, create a file system on the equivalent "md" device. (In this case, since it is disk2, it would be /dev/md2 ) mkreiserfs /dev/md2 (let it finish) Then, stop the array and re-start the array. The disk should show as formatted.
May 19, 201115 yr Author Joe, many thanks - you're a star Followed your instructions, and all worked a treat: umount /dev/md3 mkreiserfs /dev/md3 (took 20 mins or so on a 2TB drive) stopped the array and rebooted - the drive appeared as formatted and ran a parity check to be sure... Best Wishes, Judy
