What sort of network and storage device are you using? Also, why set demote_secs so low? -----Original Message----- From: linux-cluster-bounces@xxxxxxxxxx [mailto:linux-cluster-bounces@xxxxxxxxxx] On Behalf Of ffv@xxxxxxxxxxx Sent: Tuesday, November 04, 2008 2:13 PM To: linux-cluster@xxxxxxxxxx Subject: GFS2 poor performance Hi all, I´m getting a very poor performance using GFS2. I have two qmail (mail) servers and one gfs2 filesystem shared by them. In this case, each directory in GFS2 filesystem may have upon to 10000 files (mails) The problem is in performance of some operations like ls, du, rm, etc for example, # time du -sh /dados/teste 40M /dados/teste real 7m14.919s user 0m0.008s sys 0m0.129s this is unacceptable Some attributes i already set using gfs2_tool: gfs2_tool settune /dados demote_secs 100 gfs2_tool setflag jdata /dados gfs2_tool setflag sync /dados gfs2_tool setflag directio /dados but the performance is still very bad Anybody know how to tune the filesystem for a acceptable performance working with directory with 10000 files? thanks for any help -- Linux-cluster mailing list Linux-cluster@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/linux-cluster -- Linux-cluster mailing list Linux-cluster@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/linux-cluster
