Hi,
We have a Gluster volume hosting VMs for ESXi exported via Ganesha. Im getting the following messages in ganesha-gfapi.log and ganesha.log ===== [2017-02-28 07:44:55.194621] E [MSGID: 109040] [dht-helper.c:1198:dht_migration_complete_check_task] 0-vmware2-dht: <gfid:ec846aeb-50f9-4b39-b0c9-24a8b833afe6>: failed to lookup the file on vmware2-dht [Stale file handle] [2017-02-28 07:44:55.194660] E [MSGID: 133014] [shard.c:1129:shard_common_stat_cbk] 0-vmware2-shard: stat failed: ec846aeb-50f9-4b39-b0c9-24a8b833afe6 [Stale file handle] [2017-02-28 07:44:55.207154] W [MSGID: 108008] [afr-read-txn.c:228:afr_read_txn] 0-vmware2-replicate-5: Unreadable subvolume -1 found with event generation 8 for gfid 4a50127e-4403-49a5-9886-80541a76299c.

Not sending heartbeat SSDs volumes are running Gluster 3.8.9 and Ganesha V2.3.3 and the other cluster is running Gluster 3.7.19 and Ganesha V2.3.0. also, how can i get IO statics from Ganesha ? I appreciate your help. -- Respectfully Mahdi A. Mahdi
