Does not working the mailing list or is it only me who haven't get this
email?
BTW, did disappear the files from http://downloads.lustre.org?
Thank you,
tamas
ui.: I've made one more test and if I try two mount the lustre mount
point as an nfs share, it's not possible, or if it's a subdirectory of a
nfs share, it's not possible to view the files.

Dear All,
We have a really serious problem.
This weekend we upgraded our mixed 1.6.0.1 + 1.6.4.1 cluster based on
CentOS 4.4 i386 to CentOS 5.1 x86_64.
We reformatted all drbd storages, so recreated the whole cluster and
copy back from backup.
Windows clients reached the cluster through a samba server, but now it's
just not working at all.
This is my smb.conf
# testparm
Load smb config files from /etc/samba/smb.conf
Processing section "[cluster]"
Loaded services file OK.
Server role: ROLE_STANDALONE

# Global parameters
[global]
server string = Cluster gateway (SAMBA server)

[cluster]
path = /mnt/lustre
valid users = user
read only = No
create mask = 0775
guest ok = Yes
map system = Yes
oplocks = No
level2 oplocks = No
This is on CentOS 4.4, but also I tried it on Debian 4.0 and default
config with the same results.
Symptomps:
Sometimes I don't see anything in the share, sometimes, after samba
restart, I see a directory, but only for the next refresh. If I change
the mountpoint to user:user I see this in logs, otherway nothing
usually, but not always and not always after that:
[2008/04/06 23:51:25, 0] smbd/service.c:make_connection_snum(620)
'/mnt/lustre' does not exist or is not a directory, when connecting to
[cluster]
Lustre is now 1.6.4.3 x86_64
I appreciate any help.
Thank you,
tamas
