hi I took 4 servers for glusterfs, sev1 and sev 2 were used for replicate1, sev3 and sev4 were usered for replicate2, replicate1 and replicate2 were combined for nufa, there is server.vol in every server: server.vol volume posix type storage/posix option directory /mnt/data1 end-volume volume locks type features/locks subvolumes posix end-volume volume brick type performance/io-threads option thread-count 8 subvolumes locks end-volume volume server type protocol/server option transport-type tcp option auth.addr.brick.allow * subvolumes brick end-volume client.vol in sev1 volume sev1 type protocol/client option transport-type tcp option remote-host sev1 option remote-subvolume brick end-volume volume sev2 type protocol/client option transport-type tcp option remote-host sev2 option remote-subvolume brick end-volume volume sev3 type protocol/client option transport-type tcp option remote-host sev3 option remote-subvolume brick end-volume volume sev4 type protocol/client option transport-type tcp option remote-host sev4 option remote-subvolume brick end-volume volume replicate1 type cluster/replicate subvolumes sev1 sev2 end-volume volume replicate2 type cluster/replicate subvolumes sev3 sev4 end-volume volume nufa type cluster/nufa option local-volume-name replicate1 subvolumes replicate1 replicate3 end-volume volume writebehind type performance/write-behind option page-size 128KB option cache-size 1MB subvolumes nufa end-volume volume cache type performance/io-cache option cache-size 512MB subvolumes writebehind end-volume every server has a disk mounted on /mnt/data1, the disk has a capability with 40GB, so the glusterfs's total capbility is 80GB, client is in sev1, and mount the glusterfs on /mnt/data now the problem is that: when the replicate1 is nearly fullfilled, for expample when the replicate1 is 50MB free, i copy a file A bigger than 50MB into /mnt/data, file A will be created on replicate1, while the replicate1 is fullfiled, the rest of file A can not be write on replicate2,and the log in sev1 or sev2 is that: [posix.c:1736:posix_writev] posix: writev failed: No space left on device anybody can help me??? thanks very much -------------- next part -------------- An HTML attachment was scrubbed...
