Hi, We have been using gluster for about about six months now and all has been well until last Friday. Each evening the contents of one folder is disappearing and contents of two other folders are disappearing altogether. I'll post some logs below and give some details of what we are using. Any help would be appreciated as we would like to stick with Gluster but the data loss is getting a bit scary. :: Dual Opteron Box, 96Gb Ram :: Xen Cloud Platform Virtual Server :: QSAN ISCSI SAN :: VM - CentOS 5.7 - Gluster Master - glusterfs 3.2.5 - SAN Storage :: VM - CentOS 5.5 - Glusterfs Mount - glusterfs 3.1.7 - SAN Storage :: Dual Xeon Box, 24Gb RAM :: VM - CentOS 5.7 - Gluster Slave (replicating) - glusterfs 3.2.5 - Local Disk Storage A portion of the logfile for the master gluster brick...the logfile is currently sitting at 1Gb.
