Go to the first, previous, next, last section, table of contents.
Decompress every file with `chattr -c' (e.g.
find mountpoints -xdev -attr +cBD -print0 | xargs -0r chattr -c
), and then restore your kernel and the original copies of programs like
e2fsck, lsattr, chattr, and find. (It
shouldn't matter if you don't restore original copies of those
programs.)
For e2compr versions 0.4 and onwards, you must also clear a certain flag
in the superblock of each filesystem that you've had ext2-compressed
files on. You can do this with the clear-e2c program that comes
with the e2c-ancil package. See the man page or `clear-e2c --help'
for how best to use it.
(Alternatively, if you don't have clear-e2c handy but aren't
afraid to use a disk editor or dd, then just clear bit 0 from the
byte at offset 1120 of the filesystem. The offset is the same
regardless of the filesystem block size.)
