To test gluster's behavior under heavy load, I'm currently doing this on two machines sharing a common /mnt/gfs gluster mount:
ssh bal-6.example.com apt-get install dbench && dbench 6 -t 60 -D /mnt/gfs ssh bal-7.example.com apt-get install dbench && dbench 6 -t 60 -D /mnt/gfs One of the processes usually dies pretty quickly like this: [608] open /mnt/gfs/clients/client5/~dmtmp/PWRPNT/PCBENCHM.PPT failed for handle 10003 (No such file or directory) (610) ERROR: handle 10003 was not found, Child failed with status 1 And the logs are full of things like this (ignore the initial timestamp, that's from our logging): [2013-02-19 14:38:38.714493] E [afr-self-heal-common.c:2160:afr_self_heal_completion_cbk] 0-replicate0:
