Exclamation GFS clustered on LVM: error in partition size


Hello everyone,

I've a 2 node cluster with Redhat 5.6 - 64-bit with some LVM partition defined. The filesystem used is GFS clustered. I've a strange problem with one of this lvm partition about the size. The df output is as follow:

/dev/mapper/VG-LVDATA2
523969792 513024640 10945152 98% /oracle/data2

The output show that the partition size is 520Gb but the lvs output show that the partition size is 1,1Tb and from LVM gui i can't expand the partition because is at maximum of size (1,1Tb). Why the df show only 520 Gb ?!?!?!?

I must run gfs_grow to expand the partition to max size of lvm partition ?

Thanks for your support.

Bye to all !!!

Because "df" shows the filesystem size, not the partition (or in this case lv) size.
gfx_grow should fix this - maybe run ot with "-Tv" first.
