[gpfsug-discuss] SMB issues

[Simon Thompson (Research Computing - IT Services)]

Hi All,

We upgraded to 4.2.2.0 last week as well as to
gpfs.smb-4.4.6_gpfs_8-1.el7.x86_64.rpm from the 4.2.2.0 protocols bundle.

We've since been getting random users reporting that they get access
denied errors when trying to access folders. Some seem to work fine and
others not, but it seems to vary and change by user (for example this
morning, I could see all my folders fine, but later I could only see
some). From my Mac connecting to the SMB shares, I could connect fine to
the share, but couldn't list files in the folder (I guess this is what
users were seeing from Windows as access denied).

In the log.smbd, we are seeing errors such as this:

[2016/12/19 15:20:40.649580,  0]
../source3/lib/sysquotas.c:457(sys_get_quota)
  sys_path_to_bdev() failed for path [FOLDERNAME_HERE]!



Reverting to the previous version of SMB we were running
(gpfs.smb-4.3.9_gpfs_21-1.el7.x86_64), the problems go away.

Before I log a PMR, has anyone else seen this behaviour or have any
suggestions?

Thanks

Simon
