Resolving a Pending Sector
schford Posted October 29, 2015 Author Posted October 29, 2015 Had a good read and it would appear those errors are nothing to be concerned about - just double checking thats the case - if anyone could offer a second opinion would be greatful! :-)
trurl Posted October 29, 2015 Posted October 29, 2015 Had a good read and it would appear those errors are nothing to be concerned about - just double checking thats the case - if anyone could offer a second opinion would be greatful! :-) That wiki says Pending sectors occur as a result of a read failures. An unreadable sector will interfere with the reconstruction of a failed drive. Pending sectors need to be cleared as soon as possible because 2 drives with unreadable sectors will most likely be unrecoverable within unRAID. Data disks with a small number of pending sectors should be fairly easy to recover with utilities in Linux or Windows and If anyone knows of a Mac utility that can recover Reiserfs please update this entry. The safest procedure is to replace the drive with a pre-cleared spare. The original drive can then be pre-cleared and the pending sector count should go to zero. The original drive can then be used as a spare. Multiple pre-clear cycles should not be required and the disk should be RMAed if 1 cycle doesn't work. If the drive cannot be returned then multiple cycles may restore the drive to a usable state. If no spare is available then follow the next procedure to re-enable the drive. The pending sector count should be zero after rebuilding. If not then replace.
trurl Posted October 29, 2015 Posted October 29, 2015 In fact, pending sectors are one of the main things we are concerned about around here. See search tips in my sig and you can find a lot more posts about them.
