"Accidentally" destroyed my filesystem
I was trying to delete and recreate a filesystem, thinking it would be a quick way of deleting all of the files off of it, and I fear that I messed up. Here is the original entry from /etc/filesystems:
Code:
data01:
        dev             = /dev/fslv00
        vfs             = jfs2
        log             = /dev/loglv00
        mount           = true
        options         = rw
        account         = false

And the output from df:
Code:
/dev/fslv00    133169152         0  100%  4639433    60% /data01

I first ran rmfs /data01 to delete the filesystem, then I tried the following:
Code:
[root@ibm: /]# mkfs -V jfs2 -o name=/data01 /dev/fslv00
mkfs: destroy /dev/fslv00 (yes)? y
mkfs: 0506-214: /dev/fslv00: A file or directory in the path name does not exist.

This didn't work so I tried crfs instead, but I don't think I was using that properly either:
Code:
[root@ibm: dev]# crfs -m /data01 -d /dev/fslv00 -v jfs2
0516-306 getlvodm: Unable to find  fslv00 in the Device
        Configuration Database.
/usr/sbin/getlvodm: A flag requires a parameter: y
Usage: /usr/sbin/getlvodm [-a LVdescript] [-B LVdescript] [-b LVid] [-c LVid]
        [-C] [-d VGdescript] [-e LVid] [-F] [-g PVid] [-h] [-j PVdescript]
        [-k] [-L VGdescript] [-l LVdescript] [-m LVid] [-p PVdescript]
        [-r LVid] [-s VGdescript] [-t VGid] [-u VGdescript] [-v VGdescript]
        [-w VGid] [-y LVid] [-G LVdescript]
crfs: 0506-923 Cannot get logical volume type from odm.

I am just trying to recreate my old /data01 filesystem with "normal" settings. The man pages for mkfs/crfs are a little confusing.. Any help would be appreciated.

virtual-filesystems

virtual-filesystems(7)					 Miscellaneous Information Manual				    virtual-filesystems(7)

NAME

       virtual-filesystems - event signalling that virtual filesystems have been mounted

SYNOPSIS

       virtual-filesystems [ENV]...

DESCRIPTION

       The  virtual-filesystems  event	is  generated  by  the mountall(8) daemon after it has mounted all virtual filesystems listed in fstab(5).
       mountall(8) emits this event as an informational signal, services and tasks started or stopped by this event will do so	in  parallel  with
       other activity.

       This event is typically used by services that must be started in order to mount other filesystems.  When this event occurs, common filesys-
       tems such as /usr may not be mounted.  For most normal services the filesystem(7) event is sufficient.

EXAMPLE

       A service that wishes to be running once virtual filesystems are mounted might use:

	      start on virtual-filesystems

SEE ALSO

       mounting(7) mounted(7) local-filesystems(7) remote-filesystems(7) all-swaps(7) filesystem(7)
