Why does md5sum give inconsistent results on device files? md5sum sdx img gives result < foo > purge disk buffers: sudo blockdev --flushbufs dev sdx otherwise subsequent command reads disk cache and not the actual disk (as confirmed by looking at the activity light on the USB drive, and the speed of completion of later commands) sudo md5sum dev sdx gives result < bar > So it seems the copy failed BUT
Troubleshoot, Manage and Monitor Hard Disk Drive Medium Errors To stop a patrol read scan: # MegaCli64 -AdpPR -Stop -aALL Consistency Check In RAID, the Consistency Check verifies the correctness of redundant data in an array For example, in a system with parity, to check consistency means to compute the parity of the data drives and compare the results to the contents of the parity drive •
md5sum repeatedly gives different checksum for same file on . . . I have a very small and quite old hard drive disk, about 32G On to this disk I have copied a largish tar file, about 5G When I run md5sum to generate a checksum on this file I repeatedly get different results (on the same machine and the same file) This obviously should not happen
MegaRAID RAID-1 consistency check issues - ServeTheHome Forums So basically it's the filesystem that's responsible for keeping that in check Raid only provides disk redundancy in case of a disk failure A single disk can fail and your array will survive until it is replaced in the case of raid 5 or two disks can fail and your array will survive in the case of raid 6
[SOLVED] One of your disks needs to be checked for consistency. Thing is, when i click on system restore it says ''Windows has detected file system corruption on local disc C, you must check the disc for errors before it can be restored'' Then when i try and run chkdsk it says
Common RAID Performance Killers: Consistency Checks - Gillware Here you can see the command to run StorCLI and then show information on consistency checks: c0 show cc In the information that follows, we can see the current consistency check mode is Concurrent, the execution delay (when it runs) is every 168 hours, or once per week, and when the next check will run, in this case at 12:00 am of February 26th
