I need to copy a busy filesystem to another box, but I cannot afford shutting down the application that causes the filesystem noise.
Because the FS is a Veritas VxFS I was lured to believe I could tranquilize the FS to be copied by a simple FS snapshot.
At least the mount_vxfs manpage mentions a snapof option, which I tried in this fashion (after having created lvsnap abt. 10% in size of /opt/bea's LV).
# mount -F vxfs -o snapof=/opt/bea /dev/vg00/lvsnap /mnt/tmp1
vxfs mount: option not supported on this version of vxfs.
Hmm, isn't Version 3 of HP-UX's VxFS sufficient for the snapshot feature?
(On Solaris you get a working fssnap command already together with the OS!)
# fstyp -v $(awk '/\/opt\/bea/{print$1}' /etc/mnttab)
vxfs
version: 3
f_bsize: 8192
f_frsize: 8192
f_blocks: 76800
f_bfree: 12318
f_bavail: 12222
f_files: 13344
f_ffree: 3072
f_favail: 3072
f_fsid: 1073741841
f_basetype: vxfs
f_namemax: 254
f_magic: a501fcf5
f_featurebits: 0
f_flag: 0
f_fsindex: 6
f_size: 76800
Solved! Go to Solution.

Re: VxFS filesystem snapshots prerequisites on HP-UX
Is online JFS installed??
swlist -l fileset |grep -i online
You need to have online JFS installed to take FS snapshots.
with best wishes

Looks I was pampered from Solaris ;-)
