File system check failing to run on HDD in my Zgemma H7S.

[BrianG61UK]

I think the HDD may be slightly corrupt. This happened before, a long time ago, and I never found a way to fix the error. I had to reformat.

It seems daft that a hard drive error stops you running e2fsck (or whatever is used) to fix the error.

This is the error:

If the resource is busy, then you may have timeshift running or you are logging to the HDD maybe? If you can telnet to the box, maybe stop enigma with "init 4" and then "umount /dev/sda1", then "fsck.ext4 -f /dev/sda1"

Possibly HDD too full for any file shuffling??

[Joe_90]

I don't know why there would be file shuffling going on. a "df -h" command would show how much free space is available.

he only way I can seem to get fsck running is with -n and as I understand it that means the result is largely meaning less.

Oops. I had already done init 4 before all that. But accidentally deleted it from capture along with various typos.

Later: Should also add that so far everything seems to still be working.

Brian,
Are you sure that you have nothing accessing /dev/sda1? Logging or timeshift? I had an issue with my HDD last week and I just stopped timeshift and was able to umount the disk and run fsck.ext4. It found disk errors and fixed them, but obviously needs to be able to write to the partition.

[BrianG61UK]

I am an idiot.
I had a swapfile set up on the HDD.
I remember doing it, but I don't need it and I thought I had removed it. I have now.

Thanks Joe_90 for your efforts to help me.

Are you using a swap file? If so you need to disable it temporarily.
Same might apply to running Samba or FTP servers.

[Joe_90]

Think it's the swapfile @birdman - see post #8
