If i need height available with afr , did it use distribute + stripe + afr just like distribute(stripe( afr(2) 4)+stripe( afr(2) 4)+stripe( afr(2) 4)) ?? 2009-07-01 eagleeyes ???? Anand Babu Periasamy ????? 2009-07-01 14:01:14 ???? eagleeyes ??? gluster-users ??? Re: HELP: problem of stripe expansion !!!!!!!!!!!!!!!!!!!!!!!! You cannot expand stripe directly. You have to use distribute + stripe, where you scale in stripe sets. For example, if you have 8 nodes, you create => distribute(stripe(4)+stripe(4)) Now if you want to scale your storage cluster, you should do so in stripe sets. Add 4 more nodes like this: => distribute(stripe(4)+stripe(4)+stripe(4)) Distributed-stripe not only makes stripe scalable, but better load balanced and reduced disk contention. -- Anand Babu Periasamy GPG Key ID: 0x62E15A31 Blog [http://unlocksmith.org] GlusterFS [http://www.gluster.org] GNU/Linux [http://www.gnu.org] eagleeyes wrote: > Hello: > Today i test stripe expansion : two volumes expand four volumes > , when i vi or cat a file ,the log was : > [2009-07-01 11:25:55] W [stripe.c:1920:stripe_open_getxattr_cbk] stripe: client8 returned error No such file or directory > [2009-07-01 11:25:55] W [stripe.c:1920:stripe_open_getxattr_cbk] stripe: client7 returned error No such file or directory > [2009-07-01 11:25:55] W [stripe.c:1871:stripe_open_cbk] stripe: client7 returned error No such file or directory > [2009-07-01 11:25:55] W [stripe.c:1871:stripe_open_cbk] stripe: client8 returned error No such file or directory > [2009-07-01 11:25:55] W [fuse-bridge.c:639:fuse_fd_cbk] glusterfs-fuse: 149: OPEN() /file => -1 (No such file or directory) > > Did it a bug like dht expansion ?
