ERROR resize fs / (vxfs fsadm ERROR)

[Goriik]

Hi guys.

Work in LVM-maintenance mode

Successfully

lvextend-l 100 /dev/vg00/lvol1

mount /dev/vg00/lvol1 / stand1

/usr/sbin / fsadm-F vxfs-b nolargefiles / stand1

Everything went well.

I carry out for / dev/vg00/lvol3

# Lvextend-l 1950 / dev/vg00/lvol3
Logical volume "/ dev/vg00/lvol3" has been successfully extended.
Volume Group configuration for / dev/vg00 has been saved in / etc/lvmconf/vg00.conf

Checking

# Lvdisplay / dev/vg00/lvol3
--- Logical volumes ---
LV Name / dev/vg00/lvol3
VG Name / dev/vg00
LV Permission read / write
LV Status available / syncd
Mirror copies 0

LV Size (Mbytes) 1600
Current LE 50
Allocated PE 1950
Stripes 0
Stripe Size (Kbytes) 0
Bad block off
Allocation strict / contiguous
IO Timeout (Seconds) default

All of this is OK.

But while running.

What do you think is the problem?

Hi,

I have some bad news for you: the root fs just can't be extended so simply. lvol1/2/3 need to be continuously allocated on the disk. So, if you want to have a larger /, you need to restore the system from ignite, and at the start of the restore you can select a larger root.

Hi Goriik,

Best to log a call with hp support now.

hi,

as already Viktor mentioned, the best way is to make a ignote backup and in advaced recovery change the size of the / file system.

Yes of course if you have mirrored disks with a LVM, there is a way how-to resize the root partition, but it isn't officially supported.

by the way!

to extend /dev/vg00/lvol3 online ,you must have onlineJFS software installed.

good luck!
