Amit,
Cut from a web doc:

There are three primary causes for this error:

1. The file system is too busy to be resized
Â· Although resizing a file system requires that the file system be mounted, fsadm must "freeze" the file system to actually
perform the resize
Â· Freezing will temporarily prevent new accesses to the file system and fsadm must wait for pending I/O's to complete
Â· If fsadm is unable to freeze the file system quickly, it gives up stating that the file system is too busy
2. The file system has a snapshot file system mounted on it
Â· If a snapshot file system was mounted that is a "snapof" the file system being resized, the resize will fail
Â· File systems that have snapshots mounted on them cannot be resized
3. The file system may have corruption and needs to be fsck'd
Â· A file system that has experienced structural damage and is marked for full file system check cannot be resized
Error # 16 - Resolution
Â· Make sure that the file system does not have any snapshot file system mounted on it
Â· Attempt the resize when the file system has less of a load on it
Â· If fsadm continues to fail with "errno 16" then unmount the file system, perform a "fsck", remount and try again

Is error code 16 from OS or from fsadm? OS error code 16 refer to following.

#define EBUSY 16 /* Mount device busy */

Do you have enough space to reduce a FS? Reducing a file systems is not good, unless you have a good backup.

fsadm -F vxfs -b xxxxM /mount_point (if you have online jfs)
lvreduce -L xxxM /dev/vgxx/lvolx

Is that what you are doing?

Please tell us your OS type, version of OnlineJFS and the filesystem layout of the mount point you are trying to reduce.

# uname -a
# swlist -l product OnlineJFS
# fstyp -v /dev/vgxx/lvolx

thanks
