Hello,
we are playing a bit with Spectrum Scale OBJ storage. We were able to get
working unified access for NFS and OBJ but only if we use swift clients. If we
use s3 client for OBJ, all objects are owned by swift user and large objects
are multiparted wich is not suitable for unified access.
Hello,
is this bug already resolved?

And are you sure it is present only in -1062.18.1.el7 kernel? I think it is
present in all -1062.* kernels..

Hello,
I noticed this bug, it took about 10 minutes to crash.
However, I'm seeing similar NULL pointer dereference even with older kernels,
That dereference does not happen always in GPFS code, sometimes outside in NFS
or elsewhere, however it looks familiar. I have many crashdumps about this.
Hello,
is there any settings for GPFS 5.x so that you could mitigate slow down of
asymmetric SAN? The asymmetric SAN means, that not every LUN has the same
speed, or not every disk array has the same number of LUNs. It seems that
overal speed is degraded to the slowest LUN. Is there any

I noticed that from time to time, device id of a gpfs volume is not same
across whole gpfs cluster.

Hello,
does anyone know whether there is a chance to use e.g., 10G ethernet together
with IniniBand network for multihoming of GPFS nodes?
I mean to setup two different type of networks to mitigate network failures.

Hello,
did anyone encountered an error with RHEL 7.5 kernel 3.10.0-862.3.2.el7.x86_64
and the latest GPFS 4.2.3-9 with kernel NFS?
I'm getting random errors: Unknown error 521. It means EBADHANDLE. Not sure
whether it is due to kernel or GPFS.

Hello,
I'm thinking about the following setup:

I would like to setup shared scratch area using GPFS and those NVMe SSDs. Each
SSDs as on NSD.
I don't think like 5 or more data/metadata replicas are practical here. On the

Hello,
we have files about 100GB per file. Many of these files are migrated to tapes.
(GPFS+TSM, tape storage is external pool and dsmmigrate, dsmrecall are in
place).
These files are images from bacula backup system. When bacula wants to reuse
some of images, it needs to truncate the file to

I have a fileset with separate inodespace:

Just leting know, I see the same problem with 4.2.2.1 version. mmrepquota

does CES offer high availability of SMB? I.e., does used samba server provide
cluster wide persistent handles? Or failover from node to node is currently

ganesha allows to specify pseudo root for each export using Pseudo="path".
mmnfs export sets pseudo path the same as export dir, e.g., I want to export

Can I set somehow Pseudo to '/'?
