iscsi network share + xfs

Hello,

we got a MD3000i used as a network share between two servers (say A and B). The problem we are facing is that file/directories created by server A are not visible on server B (and viceversa). It's not a problem with permission (chmod 777 doesn't help).

The MD3000i was at first used ony with server A. We then added server B. All files/directories added "before B" were readable from both A and .

Here are some details:

MD3000i

Read cache: Enabled
Write cache: Enabled
Write cache without batteries: Disabled
Write cache with mirroring: Disabled
Flush write cache after (in seconds): 10.00
Dynamic cache read prefetch: Enabled


XFS filesystem.

On server A we have (from /etc/fstab)

/dev/disk/by-id/scsi-36a4badb000443c1c000003a04bf628a4-part1 /storage xfs noauto,nofail 0 0

Could be a problem with a combination of cache and xfs barriers?

Ok, solved.
filesystem xfs doesn't support clustering.Smilie

We need to use lock-aware fiesystem as OCFS, GFS or something.

NAME
kswitch - switch primary credential cache SYNOPSIS
kswitch {-c cachename | -p principal} DESCRIPTION
kswitch makes the specified credential cache the primary cache for the collection, if a cache collection is available. OPTIONS
-c cachename directly specifies the credential cache to be made primary. -p principal causes the cache collection to be searched for a cache containing credentials for principal. If one is found, that col- lection is made primary. ENVIRONMENT
kswitch uses the following environment variables: KRB5CCNAME Location of the default Kerberos 5 credentials (ticket) cache, in the form type:residual. If no type prefix is present, the FILE type is assumed. The type of the default cache may determine the availability of a cache collection; for instance, a default cache of type DIR causes caches within the directory to be present in the collection. FILES
/tmp/krb5cc_[uid] default location of Kerberos 5 credentials cache ([uid] is the decimal UID of the user). SEE ALSO
kinit(1), kdestroy(1), klist(1), kerberos(1) KSWITCH(1)
