[Gluster-devel] [Gluster-user] Sybase backup server failed to write to Gluster NFS

[Peter Auyeung]

Hi Soumya,

I was able to mount the same volume on other NFS client and do writes

got the following nfs.log entries when write




[2015-01-22 17:39:03.528405] I [afr-self-heal-common.c:2868:afr_log_self_heal_completion_status] 0-sas02-replicate-1:  metadata self heal  is successfully completed,   metadata self heal from source sas02-client-2 to sas02-client-3,  metadata - Pending matrix:  [ [ 0 0 ] [ 0 0 ] ], on /RepDBSata02
[2015-01-22 17:39:03.529407] I [afr-self-heal-common.c:2868:afr_log_self_heal_completion_status] 0-sas02-replicate-2:  metadata self heal  is successfully completed,   metadata self heal from source sas02-client-4 to sas02-client-5,  metadata - Pending matrix:  [ [ 0 0 ] [ 0 0 ] ], on /RepDBSata02

Hi Peter,

Can you please try manually mounting those volumes using any/other nfs
client and check if you are able to perform write operations. Also
please collect the gluster nfs log while doing so.

Thanks,
Soumya
