Extend Filesystem on Red Hat Linux 9 system

[Jason Berendsen]

Hopefully this is a fairly easy question.

I am new to the Red Hat realm and have the need to increase the size of my /usr filesystem. As you probably have figured I have LVM running. I extended the logical volume without a problem. I then unmounted /usr and ran
resize_reiserfs -s +200M -f /usr
I got the following error:
bread: Cannot read the block (2)

I then tried
resize_reiserfs -s +200M /dev/vg00/lvol7
I got the following error:
reiserfs_open: neither new nor old reiserfs format found on /dev/vg00/lvol7
resize_reiserfs: cannot open '/dev/vg00/lvol4': Success Aborted

Any idea what I am doing wrong?

Thanks,

Jason

Why do you use reiserfs ?
RH9 is usually using ext3. The command would rather be
resize2fs /usr with all the arguments you wish... did I miss sth ?

Thanks Jerome,

I figured I was off base with the command I was using. One more question, do you know an equivalent command to HP-UX's fsadm, where you can resize FS on line?

I don't think there is one. All Unix is not implemented in Linux, and as it's usally small systems on x86, one do not touch system settings quite often after creation.
Do you know this translation table ? Quite usefull sometimes :

Tks fr yr assignments.

Reiserfs can be grown while mounted. Ref:

Look at the man pages , and then mount options. Last option has the opportunity to resize online, and there is a link to an online resizer.

Unfortunately RH is on ext3 filesystem.
It cans still be resized (but unmounted) with parted command. If you do not know it, check at :
