Re: [ptxdist] automatic root-fs fsck at boottime with autorepair

[Marc Michalewicz <Marc.Michalewicz@railtec-systems.ch>]

Hi,

thanks for your hint; the issue is still open and I have no clue what to do next
although your answer helped a little bit.

But how/where do I have to install the check ?
Can you detail your idea a little bit more ?

I tried "fsck.ext3 -p /dev/mmvblk0p1" on the line before "mount -a ..." in rcS but this 
did not work: 
"fsck.ext3: No such file or directory while trying to open /dev/mmcblk0p1"


Just fyi in the syslog I found these lines:

Apr 21 11:50:11 [..] [ 1.854104] EXT3-fs: barriers not enabled 
Apr 21 11:50:11 [..] [12.856129] kjournald starting.  Commit interval 5 seconds 
Apr 21 11:50:11 [..] [12.856223] EXT3-fs (mmcblk0p1): warning: maximal mount count reached, running e2fsck is recommended
Apr 21 11:50:11 [..] [13.091387] EXT3-fs (mmcblk0p1): using internal journal 
Apr 21 11:50:11 [..] [13.091398] EXT3-fs (mmcblk0p1): recovery complete 
Apr 21 11:50:11 [..] [13.093917] EXT3-fs (mmcblk0p1): mounted filesystem with ordered data mode

What does all this mean in detail - especially "recovery complete" ?
so another question would be: do you think a (automatic) fsck is needed at all ?
We just encountered an issue in a mysqld-logfile upon an unexpected power-off but 
this was actually not an issue of the filesystem. Anyway I thought a fsck might be helpful sometimes.

Thanks for any help,

Marc
