[Linux-cluster] lock_nolock to lock_dlm trouble



Hello,

I had to remove a storage system from my cluster. It was formatted using lock_dlm before being removed. An then, it was plugged on a single server, using the "lockproto=lock_nolock" option.
Now, I put it back in the cluster, but I can't mount it with the standard lock_dlm (but it's ok with the lock_nolock option, but it of course prevents me to share it).

 

The error is

GFS: Trying to join cluster "lock_dlm", "alpha_cluster:vol001"
lock_dlm: new lockspace error -17
GFS: can't mount proto = lock_dlm, table = alpha_cluster:vol001, hostdata =

 

When mounted with nol_lock option, gfs_tool df /mnt/san3 says:

/mnt/san3:
  SB lock proto = "lock_dlm"
  SB lock table = "alpha_cluster:vol001"
  SB ondisk format = 1309
  SB multihost format = 1401
  Block size = 4096
  Journals = 32
  Resource Groups = 12128

There is 1.7Tb of data on this system. What can I do ?
Thank's for your help.
