Hi, I have one NAS which I can access via NFS or Samba. This storage is accessed by 2 linux servers with Samba where I re-export the NAS share. This is sort of an active/active loadbalancing cluster. The only thing not working is locking... If a client opens a Word-File via server1 and another opens the same via server2 it won't inform the user that he can only open the file readonly. I was hoping, that the NFS server will tell Samba that the file is already in use (rw) - didn't happen. When I switched from NFS to Samba on the NAS and checked the NAS-Server, Server1 and Server2 with smbstatus I see the following: NAS: Locked files: Pid Uid DenyMode Access R/W Oplock SharePath Name Time -------------------------------------------------------------------------------------------------- 6893 0 DENY_NONE 0x19b RDWR NONE /export/storage smbshare/bla/bla1.docx
Server1: Locked files: Pid Uid DenyMode Access R/W Oplock SharePath Name Time -------------------------------------------------------------------------------------------------- 2004 0 DENY_WRITE 0x2019f RDWR NONE /import/999999/smbshare bla/bla1.docx Sever2: Locked files: Pid Uid DenyMode Access R/W Oplock SharePath Name Time -------------------------------------------------------------------------------------------------- 1442 0 DENY_WRITE 0x2019f RDWR NONE /import/999999/smbshare bla/bla1.docx Of course every server has its own locking DB but why does the NAS not set DenyMode to DENY_WRITE I'd hope that this would do the trick... I also tried to use ctdb on the 2 servers but afaik it'll only work with a Cluster-FS and not with a NFS or Samba share. At least ping_pong stopped working as soon as I started it on the 2nd server. Does anyone has any idea how I can get file locking working with this setup (1 NAS and 2 active Samba servers)?
