I have an ext3 filesystem that has several directories and each directory gets a large number of files inserted and then deleted over time.
Can you specify "large number"? What do "ls large-directory | wc -l" say?
The filesystem is basically used as a temp store before files are processed. The issue is over time the directory scans get extremely slow even if the directories are empty. I have noticed the directories can range in size from 4k - 100M even when they are empty.
proably deleted-but-still-open files. When lsof(8) is installed, you can find out with: "lsof -ln | grep large-but-empty-directory"
Can you specify "slow" as well? You also might want strace(1) an "ls" on your large directory to see what is taking so long.
Is there a way to fix this without recreating the directories or bringing the filesystem offline?
You have enabled htree (dir_index) already:
Filesystem features: has_journal resize_inode dir_index filetype needs_recovery sparse_super large_file
If you've enabled dir_index after the directories have been created, you might want to "e2fsck -D" (see the manpage for details) the filesystem. For partitions with temprary files you could play with "noatime","async" and "data" mount-options (please read the manpage, really!).
Which kernel do you use? Which arch? C. -- BOFH excuse #83: Support staff hung over, send aspirin and come back LATER. _______________________________________________ Ext3-users mailing list Ext3-users@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/ext3-users
