Listing file systems in /etc/filesystems on AIX 5.1c

The Mount agent uses the fsck command to repair a corrupted file system. In a cluster running AIX 5.1c, the fsck command requires the /etc/filesystems file on each system to contain entries for all file systems referenced by the BlockDevice attribute of the Mount agent. The fsck-V vfstype filesystemname command also does not work on AIX 5.1c systems without a corresponding entry for the file system in /etc/filesystems.

The crfs command automatically adds an entry for a new file system to /etc/filesystems on the system it was created on. You must add entries to /etc/filesystems on all other systems in the cluster. The mkfs command does not add an entry for a new file system to /etc/filesystems. You must add entries to /etc/filesystems on all systems in the cluster.

Example 1

In this /etc/filesystems entry for a VxFS file system created on a VxVM volume, /mount_point is the mount point for the file system, /dev/vx/dsk/Diskgroup_name/Volume_name is the block device on which the file system is created, and vxfs is the file system type.

/etc/filesystems:

/mount_point:

dev = /dev/vx/dsk/Diskgroup_name/Volume_name

vfs = vxfs

mount = false

check = false

Example 2

In this /etc/filesystems entry for a JFS file system created on an LVM logical volume, /mount_point2 is the mount point for the file system, /dev/LVMlogical_volume is the block device on which the file system is created, /dev/LVMlogical_volumelog is the log device for the file system automatically created by the crfs command, and jfs is the file system type.

/etc/filesystems:

/mount_point2:

dev = /dev/LVMlogical_volume

vfs = jfs

log = /dev/LVMlogical_volumelog

mount = false

check = false
