Hi, I have a few questions about filesystem checking and JFS.
Firstly, are there any situations, *except* when the filesystem is not clean, where a standard invokation of jfs_fsck will cause a disk check to happen? For example, ext2/ext3 has a feature where it fsck will check the disk after X days or Y mounts even when the filesystem is clean. Secondly, is it recommended to force a check of JFS filesystems (even when clean) regularly? These systems will have approx 700GB of heavily-used JFS. For ext2/3, the tune2fs man page suggests that regular forced checking is very important - does the same apply here? Some context: I'm trying to avoid the really long startup delays while jfs_fsck scans the huge partitions, possibly by making the checks only happen on shutdown. However, I now suspect that these long startup checks are *only* running after unclean shutdowns, as opposed to being some time-based thing. In this case, moving the fs checks into the shutdown procedure would be redundant, but I am left wondering whether we should enforce time-based checks if the FS doesn't do it for us. Any clarification appreciated! Thanks, Daniel ------------------------------------------------------------------------- Using Tomcat but need to do more? Need to support web services, security?
