Issue changing fs to allow largefiles

[KURT HARLESS]

Greetings,

Attempted to change a filesystem to allow large files and received the following message;
# fsadm -F vxfs -o largefiles /u06

vxfs fsadm: /u06 is not the root inode of a vxfs file sytem

Does root need this applied to it too?

[Deepak Seth_1]

trying doing on raw device.

Hi Kurt,

Try it w/o the -F vxfs. The system will check the entry in /etc/fstab to determine FS type.
But...if not if /u06 is not in there it defaults to /etc/default/fs - then you will need to know what FS type it is.
Also note you can use -V to "preview" the command.

Rgds,
Jeff

is /u06 listed in /etc/fstab file?

[S.K. Chan]

Assuming /u06 is in /dev/vg02/lvol1 then you would run it like so ..

# fsadm -F vxfs -o largefiles /dev/vg02/rlvol1

with /u06 unmounted of course. Running it with ..

# fsadm -F vxfs -o largefiles /u06

would only work if you have OnlineJFS. I'm assuming /u06 is vxfs.

Hi,

it will work only if you have Online JFS. Is /u06 a part of the lvol ??

Try to run this command on the raw logical volume.

# fsadm -F vxfs -o largefiles /dev/vg03/rlvol3

You can always use SAM Disks and file systems/file systems choose the file system, click on actions/modify, click on Allow large files.

Some questions...

is /u06 an existing filesystem? If so you will need OnLineJFS. If all else fails go back to basics Ignore all the money you spent on it and

# fbackup -f /dev/rmt/1m -0 -i /u06
# umount /u06
# newfs -F vxfs -o largefiles /dev/vg01/ru06
(remember the r)
# mount /dev/vg01/u06 /u06
# frecover -x -f /dev/rmt/1m

Hi KURT


do a fsadm -o largefile /u06 if you ahve a online JFS installed , incase it is not there then you have to umount it to run the command.

I've had the same problem - but in reverse. Take a look at the following link where instructions (both via sam and command line) are detailed.

Good

luck.http://forums.itrc.hp.com/cm/QuestionAnswer/1,,0x1ca83a7b3682d611abdb0090277a778c,00.html

Hi,

you need to specify the raw device for the logical volume. If you don't have onlineJFs you'll have to unmount the filesystem, change the lv to largefiles and then mount the lv using the option largefiles (modify /etc/fstab).

Hope this helps.
