Subject: [Ocfs2-devel] question of dentry number
Date: Fri, 08 May 2009 15:28:35 +0800 [thread overview]
Message-ID: <4A03DF23.8090903@suse.de> (raw)
I observer interesting dentry number during the dlm stress testing. The ocfs2
cluster stack is user space "pcmk".
creating a empty directory, ls -al:
total 8
drwxr-xr-x 2 root root 4096 2009-05-08 15:29 .
drwxr-xr-x 4 root root 4096 2009-05-08 15:29 ..
run script make_panic on single node, for 10 seconds, ls -al:
total 12
drwxr-xr-x 2 root root 4096 2009-05-08 15:33 .
drwxr-xr-x 4 root root 4096 2009-05-08 15:29 ..
-rw-r--r-- 1 root root 0 2009-05-08 15:33 file0000000001
-rw-r--r-- 1 root root 459611068 2009-05-08 15:33 file0000000003
then run this script on ocfs2 volume of both nodes for 10 seconds, ls -al:
total 32
drwxr-xr-x 2 root root 4096 2009-05-08 15:34 .
drwxr-xr-x 4 root root 4096 2009-05-08 15:29 ..
-rw-r--r-- 1 root root 939787135 2009-05-08 15:34 file0000000000
-rw-r--r-- 1 root root 922127231 2009-05-08 15:34 file0000000001
-rw-r--r-- 1 root root 0 2009-05-08 15:34 file0000000002
-rw-r--r-- 1 root root 503703844 2009-05-08 15:34 file0000000003
I don't understand how there are 32 dentries in the directory. Can anybody tell
me the magic ? Or it's a bug.
Thanks.
