Rajahal Posted March 5, 2011 Share Posted March 5, 2011 I noticed something on a client build that may be a bug with 4.7, or may just be a fluke. I installed 10 precleared 2TB WD EARS (4k-aligned, no jumpers), assigned a parity drive and 9 data drives, and started off the parity sync. As expected, all the data drives appeared unformatted at first. I started off the formatting and then walked away. Normally the formatting finishes within 15 minutes at most. I came back hours later and it was still going. Finally, the parity sync had completed, the drives had all spun down, but they were all still claiming to be 'formatting'. At this point I captured the first syslog and powered down (from the system console, since I couldn't from the web GUI). I powered up again and the system immediately went into a parity check (why? was the system console powerdown unclean? I though that issue was tackled many moons ago...). All data disks still claimed to be unformatted. I clicked the format button again and captured the second syslog. Again I walked away and let it run. After a normal amount of time the parity check finished (with no errors) and all the disks were properly formatted. So at this point in time everything is normal. Still, I figured I should share this abhorrent behavior in case it is some kind of bug.

neilt0 Posted March 5, 2011 Share Posted March 5, 2011 I experienced a similar problem with 4.7 yesterday -- hit format, waited until the browser returned to idle, hit refresh on the browser and unRAID still said "unformatted disk(s) present". And it showed a format button. So I tried again. And again. After a couple more attempts, I gave up and rebooted. Then I tried the format again, and it worked first time. Link to comment
opentoe Posted March 5, 2011 Share Posted March 5, 2011 I'll be formatting a 2TB drive soon as the pre-clear is done. Even though unRAID still does another "clear" on it. Weird. Link to comment
prostuff1 Posted March 5, 2011 Share Posted March 5, 2011 I'll be formatting a 2TB drive soon as the pre-clear is done. Even though unRAID still does another "clear" on it. Weird. No, if it is precleared properly it does not do a clearing of the drive. unRAID itself does have to FORMAT the drive after it is added to the array. I have had the issue mentioned in the title happen once to me before. I don't know the exact cause of the issue but it seems like a condition of the mkreiserfs being called at essentially the same time on all drives in the system. Link to comment
Blofeld Posted March 28, 2011 Share Posted March 28, 2011 I think I'm having a related issue... I've successfully per-cleared a WD 2TB EARS (unjumpered), stopped the array, assigned it to slot 5 (sde). As expected, the server tells me that a new disk was found, I click the box that "I'm sure I want to do this" (add to array), and then hit START. Nothing happens thereafter though, even after a few more refreshes and a few more attempts. None of the disks actually come online, and I have no clue as to why. I haven't even gotten as far as seeing the "Format" button. I'm attaching a syslog, and I'm also copying also the results from the pre-clear below. Not sure if rebooting the server would help, or anything... Anyone have any insight into this? It'd be much appreciated.

You're doing it wrong then, or you don't understand what precleared means. A precleared drive can be added to an existing array as a new disk without unRAID doing it's own preclear. A precleared drive means nothing with a new array or when replacing a disk since in both of these cases either the parity or the data drive must be rebuilt. Peter Link to comment
lionelhutz Posted March 28, 2011 Share Posted March 28, 2011 Blofeld - You are getting errors on sde, which presumably is the new disk. Your issue is most likely not related to the OP's issue and it should be a seperate thread. Peter Link to comment

cobra281 Posted June 6, 2011 Share Posted June 6, 2011 I just had the same thing happen to me. I let them run for over 24 hours and still the status was "formatting". I just issued the powerdown command and the server is rebooting. I will let you know if it corrects itself with the reboot. Link to comment
cyrnel Posted June 6, 2011 Share Posted June 6, 2011 I sure I saw this two or three times when adding multiple precleared drives. Never got to the point of verifying the web interface was accurate, and it would work the next time, and then Zacate happened. Link to comment
