I have a QNAP NAS with 4 disks as a single "Striping Disk Volume: Drive 1
2 3 4 EXT4"
couple of days ago, power failed, according to QNAP log, system was
shutdown by UPS notification
when I powered it up, I tried to do 'checkdisk' using web i/face, but, it
keeps failing with:
23:23:37 System [Strip Disk Volume: Drive 1 2 3 4] Start examination.
23:32:16 System [Strip Disk Volume: Drive 1 2 3 4] Examination failed.
what sort of test can I try from console to rectify ?
