Increase size of file system

[R.O.]

Hi,

I am a HPUX system administrator and I have to increase the size of a file system in a Tru-64 system. What I see is:

$ df -k .
Filesystem 1024-blocks Used Available Capacity Mounted on
dat_domain#dat 512000 85107 370736 19% /opt/dat

Firstly, I want to know if I have enough space available and secondly I need the procedure to increase the size of this FS.

Thanks in advance and regards,

Where? on the system or the file system?

Since the file system is under "dat_domain" AdvFS domain, you can add a free disk/disk partition to it using the 'addvol' command:
# addvol /dev/disk/ dat_domain
[example: addvol /dev/disk/dsk5c dat_domain]
Note:
1) You need license to use 'addvol'. Check if you have it (by running the command)
2) You can add the volume when the file system is online. No need to unmount the file system.

The licensing command that BL meant to include is:
# lmf list full for ADVFS-UTILITIES

Also, if you don't happen to have a free partition that you can use 'addvol' on, some of the newer storage arrays support enlarging the disks presented to the OS. Tru64 then supports changing the disklabel of the existing disk on the fly and voila - your domain and all filesets in the domain - are bigger.

Hi,

You can add new HDD if you have expansion space available and add the new HDD in the existing domain.

Alternatively you can add the slice from some other free HDD Available.

Can you send me output of volume and domain for the one that you want to expand...

if my suggestion will be ok with you please let me know and i will send you the detailed procedure for the same.

Hi,

Thank you all for your responses. Manish, I am used to working with HPUX and I don´t know anything about Tru 64... Please, tell me what comands I have to execute to give you the info you are asking me for...

Commands (assuming you're on Tru64 5.x):

# hwmgr -view device | grep disk
# ls -lR /etc/fdmns
For each disk device in the output of 'hwmgr':
# disklabel -r /dev/rdisk/dsknnc
(Note the insertion of the 'r' in rdisk in this command.)

Hi please run the commands as suggested by mark apart from that also run the following command and post the output.

df -kh
voldisk list
volinfo
voldg list

and also specify in "df -k" which parttion you need to extend.

Do you have error in some disk or some other problem why the vold daemon is not running...

can you check it and then run the command

voldisk list & df -kh

Also let me know in which domain you want to add new HDD "Shared or Local".

Manish,

I don't think vold would be running if the user has not configured LSM on the system.
