I have question related to extending JFS size to new size of LV (using LVM), I found that I have to use
mount -o remount,resize mountpoint
and also that there were some problems related to older kernels and in these cases exact size should be used like
mount -o remount,resize=1048576 mountpoint
So my question is, if there is some outage during this procedure, because this filesystem is exported with NFS
and I need to do it online without any outage.
Does anybody have some experiences with JFS resizing?
used kernel : 2.6.32-5-amd64
