We are getting error "maximal mount count reached, running e2fsck is recommended"

Rebooting the box may workaround the issue, but not fix it or tell you what was. I can't find any known issue with that error, at least with a quick search in askf5.

If the error is valid, is basically saying that you reach the maximum of mounts for that mount point.

Run these commands and it will tell you what is the mount point:

lvscan | cut -d"'" -f2 > /shared/tmp/volumes.txt
while read line; do echo $line && tune2fs -l $line | grep -i "Mount count" ; done < /shared/tmp/volumes.txt

If nothing has passed the maximum, yes is a bug.
