Hello, I try to configure glusterfs with 3 servers on centos platform. After follow the way on howtoforge, i get some error when i try to looks with "df -h", or "ls". Here is the output ; ================================================================== [root@sys-testbed3 glusterfs]# mount /dev/mapper/VolGroup00-LogVol00 on / type ext3 (rw) proc on /proc type proc (rw) sysfs on /sys type sysfs (rw) devpts on /dev/pts type devpts (rw,gid=5,mode=620) /dev/hda1 on /boot type ext3 (rw) tmpfs on /dev/shm type tmpfs (rw) none on /proc/sys/fs/binfmt_misc type binfmt_misc (rw) sunrpc on /var/lib/nfs/rpc_pipefs type rpc_pipefs (rw) glusterfs#/etc/glusterfs/glusterfs.vol on /mnt/glusterfs type fuse (rw,allow_other,default_permissions,max_read=131072) [root@sys-testbed3 glusterfs]# df -h Filesystem Size Used Avail Use% Mounted on /dev/mapper/VolGroup00-LogVol00 8.9G 3.2G 5.3G 38% / /dev/hda1 99M 34M 61M 36% /boot tmpfs 189M 0 189M 0% /dev/shm df: `/mnt/glusterfs': Transport endpoint is not connected [root@sys-testbed3 glusterfs]# ls /mnt/glusterfs ls: /mnt/glusterfs: Transport endpoint is not connected [root@sys-testbed3 glusterfs]# ll /mnt/glusterfs ls: /mnt/glusterfs: Transport endpoint is not connected [root@sys-testbed3 glusterfs]# ll /mnt/ total 0 ?--------- ? ? ? ? ? glusterfs [root@sys-testbed3 glusterfs]# ================================================================== What it mean from that error ? I really still not understand how the concept of this gluster work. I have a plan to building cluster for storage server. The idea is, if the capacity of the current storage cluster system will empty i just add the new server with full storage and so on. So i can get more new capacity after adding a new server on the fly (maybe it could be Like youtube.com storage server). Can I do this with glusterfs ? Please help me to do this, and correct me if i have something wrong here and sorry for my bad english. Regards, Parapat
GlusterFS was working fine, but it looks like a replicating system Okay, finally i was succes to make the glusterfs works for me. After i try the configuration, i still not looks that glusterfs still not able to combine all resources harddrive be one unity storage. But i still have the questions here. Are the glusterfs can combine all resources harddrive on another server to be one unity ? Is there anybody can help me how to do this ? Thank you for your response.
Yes, you can set up a kind of network RAID1 with GlusterFS, and you can also combine multiple hard drives to one big storage.
Hello Falko, Thanks for your reply. I am glad you reply my question. Falko, can you help me what is it mean about for this log : "Volume 'bricks', line 49: type 'cluster/unify' is not valid or not found on this machine" ? When I try to make unify, but the system always show that log. Let me shared my client configuration here ; ################ glusterfs.vol client configuration ############################# volume client1 type protocol/client option transport-type tcp option remote-host 192.168.0.5 option transport.socket.remote-port 6996 option remote-subvolume brick1 end-volume volume client2 type protocol/client option transport-type tcp option remote-host 192.168.0.6 option transport.socket.remote-port 6997 option remote-subvolume brick2 end-volume volume bricks type cluster/unify option namespace client-ns subvolumes client1 client2 option self-heal background option scheduler alu option alu.limits.min-free-disk 5% option alu.limits.max-open-files 10000 option alu.order disk-usage:read-usage:write-usagepen-files-usage:disk-speed-usage option alu.disk-usage.entry-threshold 2GB option alu.disk-usage.exit-threshold 128MB option alu.open-files-usage.entry-threshold 1024 option alu.open-files-usage.exit-threshold 32 option alu.read-usage.entry-threshold 20 option alu.read-usage.exit-threshold 4 option alu.write-usage.entry-threshold 20 option alu.write-usage.exit-threshold 4 option alu.disk-speed-usage.entry-threshold 0 option alu.disk-speed-usage.exit-threshold 0 option alu.stat-refresh.interval 10sec option alu.stat-refresh.num-file-create 10 end-volume ################### End of glusterfs.vol client configuration ###################### And here is configuration for 1 of the server ###################### glusterfsd.vol server configuration ###################### volume posix2 type storage/posix # POSIX FS translator option directory /data/export end-volume volume brick2 type features/posix-locks option mandatory on subvolumes posix2 end-volume volume server type protocol/server option transport-type tcp option transport.socket.listen-port 6997 # Default is 6996 subvolumes brick2 option auth.addr.brick2.allow * end-volume ############### End of glusterfsd.vol server configuration ######################## What i Want here is, I want to use all storage space from all server without use replication. Thanks before for your answers, Falko.
Okay, now i know what is mean of "type 'cluster/unify' is not valid or not found on this machine". I try to debug, and it try to load the "unify" module on my system. But the file is not there. So i try to search the file with "locate unify.so" and copy it to the directory that glusterfs wants. And it working. But I still have an issue here. I don't know how to make the script configuration for "ioctl". I still get the message error is ; "glusterfs: end of file- Inappropriate ioctl for device. Is there anybody know how to make the script for this ?
