growfs-problem "Not owner"

2008-2-13 9:30:00

Hi codeprof,

I have a problem when expanding a mounted ufs-filesystem (/var) with "growfs"
under Solaris 2.6 with SDS on a E-250.

Before the growfs i have expanded the metadevice with an additional disk-slice.
When I run:
# growfs -s 11422971 -M /var /dev/md/rdsk/d34

which results finaly in the mkfs-command:
# /usr/lib/fs/ufs/mkfs -G -M /var /dev/md/rdsk/d34 11422971

I get the following error message:
/var: Not owner

When I truss the command I get the following relevant lines (more attached):
open64("/var", O_RDONLY) = 4
ioctl(4, 0x20006640, 0x0002C570) Err#1 EPERM

in errno.h this error means:
#define EPERM 1 /* Not super-user */

But I _am_ the super-user (root).
And root _is_ the owner of /var.
And /var is a _local_ ufs-filesystem (_not_ NFS-mounted ...)

On a test-machine (Solaris 8, not /var though) growfs works fine!

Has anyone an idea what the problem (and of course the solution) could be?

Regards
