Subject: [PATCH 26/46] e2fsck: fix last mount/write time when e2fsck is forced
|
|
|
a77133 |
Content-Type: text/plain
|
|
|

|
|
|
a77133 |
With commit c52d930f e2fsck is no longer able to fix bad last
|
|
|
a77133 |
mount/write time by default because it is conditioned on s_checkinterval
|
|
|
a77133 |
not being zero, which it is by default.
|
|
|
a77133 |
|
|
|
a77133 |
One place where it matters is when other e2fsprogs tools require to run
|
|
|
a77133 |
full file system check before a certain operation. If the last mount
|
|
|
a77133 |
time is for any reason in future, it will not allow it to run even if
|
|
|
a77133 |
full e2fsck is ran.
|
|
|
a77133 |
|
|
|
a77133 |
Fix it by checking the last mount/write time when the e2fsck is forced,
|
|
|
a77133 |
except for the case where we know the system clock is broken.
|
|
|
a77133 |
|
|
|
a77133 |
[ Reworked the conditionals so error messages claiming that the last
|
|
|
a77133 |
write/mount time were corrupted wouldn't be always printed when the
|
|
|
a77133 |
e2fsck was run with the -f option, thus causing 299 out of 372
|
|
|
a77133 |
regression tests to fail. -- TYT ]
|
|
|
a77133 |
|
|
|
a77133 |
Fixes: c52d930f ("e2fsck: don't check for future superblock times if checkinterval == 0")
