[SOLVED] e2fsck stalls at 1.73%

RandomTroll · 04-04-2020, 11:09 AM

Code:

 e2fsck -ccfy /dev/sdc1

returned:

Quote:

e2fsck 1.45.6 (20-Mar-2020)
Checking for bad blocks (non-destructive read-write test)
Testing with random pattern: 1.73% done, 5:17 elapsed. (0/0/0 errors)

where it stuck for an hour.

Code:

 e2fsck -cfy /dev/sdc1

doesn't stick there, finishes in 20 minutes.

That the time stalls, not just the progress, indicate that e2fsck has stalled, not just found a sector that puzzles it so that it can't proceed? Or is the updating of time dependent on the progress of the program?

I can guess only: e2fsck examines the disk and you will see "nothing" when the disk itself works on the current I/O request. Probably some internal housekeeping...
Can you reproduce it?

I don't think I understand this comment. I would hope the time-keeping works off the timer interrupt, independently of what the program reads from the disk.

It happens every time. I gave up. The disk has worked for 11 years.

the disk has its own OS. The system (any PC, linux, windows, whatever) can only ask that OS to do something (usually read or write). But in this case it is some kind of housekeeping (or similar?) and the kernel just waits for the response. Cannot do anything [else] as long as the process is running (=no response from the disk).

Probably the disk is over, probably the best you can do is to replace it.
(and probably smartctl can give you more info, but probably that is not relevant any more)

Nah, just specifying the block size made it work.
