fs_fsck_opt "-s"

fs_type "vxfs"

A logical volume can be created in an LVM volume group, a Veritas VxVM disk group, or a Veritas CVM disk group. Logical volumes can be entered in any order, regardless of the type of storage group. The parameter explanations that follow provide more detail.

For an NFS-imported file system, see the discussion under fs_name (page 251) and fs_server (page 251).

concurrent_fsck_operations

The number of concurrent fsck operations allowed on file systems being mounted during package startup.

Legal value is any number greater than zero. The default is 1.

If the package needs to run fsck on a large number of file systems, you can improve performance by carefully tuning this parameter during testing (increase it a little at time and monitor performance each time).

concurrent_mount_and_umount_operations

The number of concurrent mounts and umounts to allow during package startup or shutdown.

Legal value is any number greater than zero. The default is 1.

If the package needs to mount and unmount a large number of file systems, you can improve performance by carefully tuning this parameter during testing (increase it a little at time and monitor performance each time).

fs_mount_retry_count

The number of mount retries for each file system. Legal value is zero or any greater number. The default is zero.

If the mount point is busy at package startup and fs_mount_retry_count is set to zero, package startup will fail.

If the mount point is busy and fs_mount_retry_count is greater than zero, the startup script will attempt to kill the user process responsible for the busy mount point (fuser -ku) and then try to mount the file system again. It will do this the number of times specified by fs_mount_retry_count.

If the mount still fails after the number of attempts specified by fs_mount_retry_count, package startup will fail.

This parameter is in the package control script for legacy packages. See “Configuring a Legacy Package” (page 302).

fs_umount_retry_count

The number of umount retries for each file system. Replaces FS_UMOUNT_COUNT, which is still supported in the package control script for legacy packages; see “Configuring a Legacy Package” (page 302).

Legal value is any greater number greater than zero. The default is 1. Operates in the same way as fs_mount_retry_count (page 250).
