Hi, i noticed a strange behavior with NFS and Glusterfs 3.2.0 , 3 of our Servers are loosing the Mount but when you restart the Volume on the Server it works again without a remount. On the server i noticed this entries in the Glusterfs/Nfs log-file when the mount on the Client becomes unavailable : [2011-06-08 14:37:02.568693] I [afr-inode-read.c:270:afr_stat] 0-ksc-replicate-0: /: no child is up [2011-06-08 14:37:02.569212] I [afr-inode-read.c:270:afr_stat] 0-ksc-replicate-0: /: no child is up [2011-06-08 14:37:02.611910] I [afr-inode-read.c:270:afr_stat] 0-ksc-replicate-0: /: no child is up [2011-06-08 14:37:02.624477] I [afr-inode-read.c:270:afr_stat] 0-ksc-replicate-0: /: no child is up [2011-06-08 14:37:04.288272] I [afr-inode-read.c:270:afr_stat] 0-ksc-replicate-0: /: no child is up [2011-06-08 14:37:04.296150] I [afr-inode-read.c:270:afr_stat] 0-ksc-replicate-0: /: no child is up [2011-06-08 14:37:04.309247] I [afr-inode-read.c:270:afr_stat] 0-ksc-replicate-0: /: no child is up [2011-06-08 14:37:04.320939] I [afr-inode-read.c:270:afr_stat] 0-ksc-replicate-0: /: no child is up [2011-06-08 14:37:04.321786] I [afr-inode-read.c:270:afr_stat] 0-ksc-replicate-0: /: no child is up [2011-06-08 14:37:04.333609] I [afr-inode-read.c:270:afr_stat] 0-ksc-replicate-0: /: no child is up [2011-06-08 14:37:04.334089] I [afr-inode-read.c:270:afr_stat] 0-ksc-replicate-0: /: no child is up [2011-06-08 14:37:04.344662] I [afr-inode-read.c:270:afr_stat] 0-ksc-replicate-0: /: no child is up [2011-06-08 14:37:04.352666] I [afr-inode-read.c:270:afr_stat] 0-ksc-replicate-0: /: no child is up [2011-06-08 14:37:04.354195] I [afr-inode-read.c:270:afr_stat] 0-ksc-replicate-0: /: no child is up [2011-06-08 14:37:04.360446] I [afr-inode-read.c:270:afr_stat] 0-ksc-replicate-0: /: no child is up [2011-06-08 14:37:04.369331] I [afr-inode-read.c:270:afr_stat] 0-ksc-replicate-0: /: no child is up [2011-06-08 14:37:04.471556] I [afr-inode-read.c:270:afr_stat] 0-ksc-replicate-0: /: no child is up [2011-06-08 14:37:04.480013] I [afr-inode-read.c:270:afr_stat] 0-ksc-replicate-0: /: no child is up [2011-06-08 14:37:05.639700] I [afr-inode-read.c:270:afr_stat] 0-ksc-replicate-0: /: no child is up [2011-06-08 14:37:05.652535] I [afr-inode-read.c:270:afr_stat] 0-ksc-replicate-0: /: no child is up [2011-06-08 14:37:07.578469] I [afr-inode-read.c:270:afr_stat] 0-ksc-replicate-0: /: no child is up [2011-06-08 14:37:07.588949] I [afr-inode-read.c:270:afr_stat] 0-ksc-replicate-0: /: no child is up [2011-06-08 14:37:07.590395] I [afr-inode-read.c:270:afr_stat] 0-ksc-replicate-0: /: no child is up [2011-06-08 14:37:07.591414] I [afr-inode-read.c:270:afr_stat] 0-ksc-replicate-0: /: no child is up [2011-06-08 14:37:07.591932] I [afr-inode-read.c:270:afr_stat] 0-ksc-replicate-0: /: no child is up [2011-06-08 14:37:07.592596] I [afr-inode-read.c:270:afr_stat] 0-ksc-replicate-0: /: no child is up [2011-06-08 14:37:07.639317] I [afr-inode-read.c:270:afr_stat] 0-ksc-replicate-0: /: no child is up [2011-06-08 14:37:07.652919] I [afr-inode-read.c:270:afr_stat] 0-ksc-replicate-0: /: no child is up [2011-06-08 14:37:09.332435] I [afr-inode-read.c:270:afr_stat] 0-ksc-replicate-0: /: no child is up [2011-06-08 14:37:09.340622] I [afr-inode-read.c:270:afr_stat] 0-ksc-replicate-0: /: no child is up [2011-06-08 14:37:09.349360] I [afr-inode-read.c:270:afr_stat] 0-ksc-replicate-0: /: no child is up [2011-06-08 14:37:09.349550] I [afr-inode-read.c:270:afr_stat] 0-ksc-replicate-0: /: no child is up [2011-06-08 14:37:09.360445] I [afr-inode-read.c:270:afr_stat] 0-ksc-replicate-0: /: no child is up [2011-06-08 14:37:09.369497] I [afr-inode-read.c:270:afr_stat] 0-ksc-replicate-0: /: no child is up [2011-06-08 14:37:09.369752] I [afr-inode-read.c:270:afr_stat] 0-ksc-replicate-0: /: no child is up [2011-06-08 14:37:09.382097] I [afr-inode-read.c:270:afr_stat] 0-ksc-replicate-0: /: no child is up [2011-06-08 14:37:09.382387] I [afr-inode-read.c:270:afr_stat] 0-ksc-replicate-0: /: no child is up Thx for the help
This can happen if all your servers were unreachable for a few seconds. The situation must have rectified during the restart. We could confirm if you change the log level on nfs to DEBUG and send us the log.
