checkfs

[jpeters]

Is there a way to get e2fsck running from the boot options (eg "e2fsck /dev/hda3") ? I recently had some serious problems on /hda3 that e2fsck found and repaired. "checkfs" seems useless.  I had to run this from puppy where I could umount /hda3 since tinycore.gz is on my hda3 partition.  e2fsck was even able to find and repair a circular dir structure error that was impossible to delete by any other method, in addition to all kinds of ionode issues.  "checkfs" didn't find anything.

If I remember correctly, "tc checkfs" calls e2fsck anyway - maybe it's a question of which command line switches are used?

hmm.....I added "checkfs"  to my boot options, and it seemed to run.  Then I went into puppy, umounted hda3, and just ran "e2fsck /dev/hda3",which straightened out all the disk problems that checkfs didn't find.

edit:  as I recall, checkfs found some problems, like the circular dir structure (link to '.'), but didn't offer to fix anything, (maybe it's defaulting to the 'n' option).

I ran 'e2fsck /dev/hda3' after booting 'base norestore', and seemed to get a much more thorough file system check/fix then I got using 'checkfs', which hardly did anything.  Here is the e2fsck:

e2fsck is called with both options f and p, force check and automatic repair.
However, I see it is called backgrounded, This happened when most processes were backgrounded to speed boot time.  checkfs is not a normal boot process and therefore should not be. I will fix in final 2.0.
