Is there a way to make fsck -a on mounted filesystem for ext3?
No. None of the popular Filesystems support online fsck.
However, if you're using pacemaker the RA (IIRC) has the option of doing an 'fsck -p' before mounting. OTOH, since an fsck has no predicatable run time limit, a long fsck might cause a 'failed start' condition, causing a cascade from one node to another to another ...
(more details on this mechanism are probably more appropriate to the applicable HA lists)
"doing an 'fsck -p' before mounting" still means you have to take the fs offline though so this doesn't really change anything.
