I have now redone the cluster using the latest and greatest following the above guide and repeated the same test I was doing before (the rsync while loop) with success. I let (forgot) it run for about a day and it was still chugging along nicely when I aborted it, so success there! On to the next test; the catastrophic failure test- where one of the servers dies, I'm having a more difficult time with. 1) I start with mounting the share over NFS 4.1 and then proceed with writing a 8 GiB large random data file with 'dd', while "hard-cutting" the power to the server I'm writing to, the transfer just stops indefinitely, until the server comes back again. Is that supposed to happen? Like this: # dd if=/dev/urandom of=/var/tmp/test.bin bs=1M count=8192 # mount -o vers=4.1 hv03v.localdomain:/data /mnt/ # dd if=/var/tmp/test.bin of=/mnt/test.bin bs=1M status=progress 2434793472 bytes (2,4 GB, 2,3 GiB) copied, 42 s, 57,9 MB/s (here I cut the power and let it be for almost two hours before turning it on again) dd: error writing '/mnt/test.bin': Remote I/O error 2325+0 records in 2324+0 records out 2436890624 bytes (2,4 GB, 2,3 GiB) copied, 6944,84 s, 351 kB/s # umount /mnt Here the unmount command hung and I had to hard reset the client. 2) Another question I have is why some files "change" as you copy them out to the Gluster storage? Is that the way it should be? This time, I deleted eveything in the destination directory to start over: # mount -o vers=4.1 hv03v.localdomain:/data /mnt/ # rm -f /mnt/test.bin # dd if=/var/tmp/test.bin of=/mnt/test.bin bs=1M status=progress 8557428736 bytes (8,6 GB, 8,0 GiB) copied, 122 s, 70,1 MB/s 8192+0 records in 8192+0 records out 8589934592 bytes (8,6 GB, 8,0 GiB) copied, 123,039 s, 69,8 MB/s # md5sum /var/tmp/test.bin 073867b68fa8eaa382ffe05adb90b583 /var/tmp/test.bin # md5sum /mnt/test.bin 634187d367f856f3f5fb31846f796397 /mnt/test.bin # umount /mnt Thanks in advance! /K _______________________________________________ Gluster-users mailing list Gluster-users@xxxxxxxxxxx https://lists.gluster.org/mailman/listinfo/gluster-users
