Hi Jorgen,
Errno 16 means "Mount device busy". There are three primary causes for this
error:
1. The file system is too busy to be resized.
Although resizing a file system requires that the file system be
mounted, one must "freeze" the file system to actually perform the resize.
Freezing will temporarily prevent new accesses to the file system, but it is
necessary to wait for pending I/O's to complete. If it is not possible to
freeze the file system quickly, stating
that the file system is too busy is given up.
2. The file system has a snapshot file system mounted on it.
If a snapshot file system was mounted on the file system being
resized, the resize will fail. File systems that have
snapshots mounted on them cannot be resized.
3. The file system may have corruption and needs to be fsck'd.
A file system that has experienced structural damage and is marked
for full fsck cannot be resized.
RESOLUTION:
Make sure that the file system does not have any snapshot file system
mounted on it. Attempt the resize when the file system has less of a
load on it.
If it continues to fail with "errno 16" then unmount the file system,
perform "fsck -o full", remount, and try again.

Hi,
Just tried to resize a volume in Storage Foundation 4.1, and ended up with
the following error:
UX:vxfs fsadm: ERROR: V-3-20340: attempt to resize
/dev/vx/rdsk/dummydg/dummyvol01 failed with errno 16 VxVM vxresize ERROR
V-5-1-7514 Problem running fsadm command for volume dummyvol01, in diskgroup
dummydg
When I tried to fsck the volume, it just aborted. This is an Oracle Rac
configuration, and I used the fsclustadm showprimary and fsclustadm
setprimary together with vxdctl c mode to assure the right host for the
operation. The vxresize command was issued from VEA, and it made the volume
unusable, and took down the entire production cluster. The issue was resolved
by resizing the volume manually with vxassist, and then fsck on the volume.
Everything is now back to normal, but why did this happen ? Anyone ?
