- Getting Help
a. Verify there is enough free space on the
NAS volume or expand it.
b. Verify that the accessed NAS volume is not
a target of a replication.
Mixed File Ownership Denied
Description Both file owner and group owner must be from the
same identity type (either UNIX or NTFS). An
attempt to set different identity types was
detected.
Cause It is impossible to change only the file owner ID to
UID if the original file ownership is SID/GSID.
Workaround To change the file ownership to UNIX style
ownership, set UID and GID at the same time.
Problematic SMB Access From A Linux Client
Description A Linux/UNIX client is trying to mount a NAS
cluster solution share using SMB (using /etc/fstab
or directly using smbmount).
A Linux/UNIX client is trying to access the file
system using the smbclient command, such as:
smbclient //<nas>/<share> -U user
%password -c ls
Workaround It is recommended that you use the NFS protocol
interfaces to access the NAS cluster solution
FluidFS systems from Linux/UNIX clients. To
workaround this issue:
1. Ensure that your admin creates NFS exports to
same locations that you use to access using
CIFS and connect to them using mount
command from Linux/UNIX clients.
2. Use NFS-based interfaces to access the NAS
cluster solution. For example, from the
NAGIOS Linux management system, use the /
check_disk command instead of the /
check_disk_smb
command.
Strange UID And GID Numbers On Dell NAS System Files
Description New files created from Ubuntu 7.x clients get the
UID and GID of 4294967294 (nfsnone).
Cause By default, Ubuntu 7.x nfs clients do not specify rpc
credentials on their nfs calls. As a result, files
created from these clients, by any user, are owned
by 4294967294 (nfsnone) UID and GID.
Workaround To force UNIX credentials on NFS calls, add the
sec=sys option to the NAS cluster solution mounts
in the Ubuntu fstab file.
