ext3 partition size

12-29-2009, 05:06 AM

Hi all,

*** I am running fedora 11 with kernel 2.6.30.9-102.fc11.x86_64 #1 SMP
Fri Dec 4 00:18:53 EST 2009 x86_64 x86_64 x86_64 GNU/Linux. I am
noticing a partition on* my drive is reporting incorrect size with
"df", the partition is ext3 size 204GB with about 79GB actual usage,
the "df" result show the partition size to be 111GB, 93GB is missing.
Please advice on what can be done to see why the system is reporting
incorrect partition size.

It definitely looks strange. Did you resize this partition after it
was created? In any case, running "resize2fs /dev/sdb8" should
enlarge the

filesystem to fill the partition.

Andreas.... thanks for the suggestion, I did a resize2fs -d -p
/dev/sdb8* on the partition* and is now showing the size and disk
usage correctly.

Thanks for your advise.
