I have a couple of samba shares from the 11 TB array (all of themare on the 11TB array). The strange behavior is that if i "ls -al /home/data", i have to wait 7-8 seconds to see the output. If i do a simple ls, output is instantaneous. I see about the same delay when i access the samba shares from the server (related ?). I don't know where to start with this!
This sounds like it might be an issue with cacheing user info.
Do you have a remote authentication server, e.g., LDAP? Are you running nscd or sssd? Does re-starting the cacheing daemon help?
Hi Paul,
You were right: I turned off SMB, NMB & Winbind and ls -al on the large array become fast as usual. Digging a little deeper, i found that some of the sub-directories in /home/data had been restored from another server and that they showed in unknown group "10432" in ls -al . So i just did:
[root@radium home]# chgrp -R "domain users" /home/data
So in conclusion, it seems that my "ls -al" on the filesystem containing unknown GID translated into queries to Active Directory and for whatever reason, resulted in a delay of several seconds (like 10-15 seconds).
Thanks Paul again.
