Hi all, cman-2.0.84-2.el5 gfs2-utils-0.1.44-1.el5_2.1 gfs-utils-0.1.17-1.el5 kmod-gfs-0.1.23-5.el5 kmod-gfs2-1.92-1.1.el5 kmod-gfs2-PAE-1.92-1.1.el5 kmod-gfs-PAE-0.1.23-5.el5 openais-0.80.3-15.el5 rgmanager-2.0.38-2.el5 Red Hat Enterprise Linux Server release 5.2 (Tikanga) kernel 2.6.18-92.1.10.el5PAE We are running the standard GFS1 that came with RedHat 5.2. We have a GFS filesystem mounted over iSCSI. When doing an 'ls' on directories with several thousand files it takes around 10 minutes to get a response back - # time ls real 8m58.704s user 0m1.369s sys 1m32.641s # ls | wc -l 120359 We only have this issue on directories with thousands of files in. Can anyone recommend any GFS tunables to help us out here ? Should we set statfs_fast to 1 ? What about glock_purge ? Here is the fstab entry for the GFS filesystem: /dev/vggfs/lvol00 /apps gfs _netdev 1 2 Here is gfs_tool df /apps /apps: SB lock proto = "lock_dlm" SB lock table = "TEST:GFS1" SB ondisk format = 1309 SB multihost format = 1401 Block size = 4096 Journals = 4 Resource Groups = 3342 Mounted lock proto = "lock_dlm" Mounted lock table = "TEST:GFS1" Mounted host data = "jid=1:id=65537:first=0" Journal number = 1 Lock module flags = 0 Local flocks = FALSE Local caching = FALSE Oopses OK = FALSE Type Total Used Free use% ------------------------------------------------------------------------ inodes 5159283 5159283 0 100% metadata 5162977 165010 4997967 3% data 208673972 62025003 146648969 30% Here is the output of gfs_tool gettune /apps | sort atime_quantum = 3600 complain_secs = 10 demote_secs = 300 depend_secs = 60 entries_per_readdir = 32 glock_purge = 0 greedy_default = 100 greedy_max = 250 greedy_quantum = 25 ilimit1 = 100 ilimit1_min = 1 ilimit1_tries = 3 ilimit2 = 500 ilimit2_min = 3 ilimit2_tries = 10 incore_log_blocks = 1024 inoded_secs = 15 jindex_refresh_secs = 60 lockdump_size = 131072 logd_secs = 1 max_atomic_write = 4194304 max_mhc = 10000 max_readahead = 262144 new_files_directio = 0 new_files_jdata = 0 prefetch_secs = 10 quota_account = 1 quotad_secs = 5 quota_enforce = 1 quota_quantum = 60 quota_scale = 1.0000 (1, 1) quota_simul_sync = 64 quota_warn_period = 10 reclaim_limit = 5000 recoverd_secs = 60 rgrp_try_threshold = 100 scand_secs = 5 stall_secs = 600 statfs_fast = 0 statfs_slots = 64 Any help appreciated Regards, Nick. -- Linux-cluster mailing list Linux-cluster@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/linux-cluster
