Hi Jonathan,
Might be a bit of a long shot this - but for copying NFSv4 ACLs between
GPFS filesystems using rsync, I had to patch rsync with some code
released by IBM at some point. We've got that patched rsync hosted on
the gpfsug github:
https://github.com/gpfsug/gpfsug-tools/tree/master/bin/rsync
Since you're not doing gpfs -> gpfs, it might be no use - but you never
know!
Oh - and, of course, make sure your GPFS filesystem is configured to
support NFSv4 ACLs.
Here's our smb.conf settings related to GPFS, ACLs and other bits and bobs:
vfs objects = shadow_copy2, fileid, gpfs
clustering = yes
fileid:mapping = fsname
gpfs:sharemodes = No
gpfs:getrealfilename = no
nfs4: mode = simple
nfs4: chown = yes
nfs4: acedup = merge
force unknown acl user = yes
acl group control = no
map acl inherit = yes
inherit acls = no
dos filemode = no
map readonly = no
map hidden = no
map archive = no
map readonly = no
ea support = yes
store dos attributes = yes
gpfs:winattr = yes
max protocol = SMB2
shadow:fixinodes = yes
shadow:snapdir = .snapshots
shadow:basedir = /exports/nas
use sendfile = yes
wide links = no
unix extensions = no
Hope that helps,
Orlando

Hi, and welcome, Jonathan.
Which combination of -A and -X rsync options did you use?

Hello, I'm new to this list, as well as GPFS.
We have new (installed over the last 6 weeks) GPFS cluster that we are
currently trying to get into service. The NSDs are running on Red Hat (6
NSDs), the storage is DCS3700 directly attached via SAS. We are running
GPFS 3.5.0.12.
Some of the data that will be placed on this cluster will be existing data
coming from other sources, one of which is our NAS (Isilon, supporting both
NFS and CIFS). We have tried a few different ways of copying the data.
First we tried to rsync directly between an NSD and one of the Isilon nodes.
Unfortunately, it appears the rsync doesn't work with the ACL format used on
the Isilon. We have also tried using various methods of copying data via
CIFS, but we continue to have no luck getting ACLs to copy. We know that,
for instance, copying data via CIFS into the Isilon using robocopy will
preserve the ACLs, and we were hoping that would work for getting data onto
GPFS as well. However, the ACLs are being stripped and replaced with
whatever ACL is present on GPFS. Does anyone have experience doing
something like that who can give me some pointers on what my configuration
should look like? I assume there are samba and/or GPFS parameters that need
to be tweaked in order to make this work, especially since this
functionality would have to be present in SONAS.
