Hi,
I have a centos 4 box i use for a file server (nfs and samba). It has two hdd:
hda is for the standard install; hdb is for /export/samba/netdisk0
hda is lost - it just clicks now
i think hdb is still good
i can't figure out how i can remount the hdb disk in a new machine and
retrieve the info from it; i've scanned the LVM howto and googled some LVM
topics, but nothing seems to address my particular need
i was oblivious to LVM until now, so i did not save anything from the /etc dir
on the hda disk
can someone help me get a clue?
thanks much,
--
mike

But the logical order of operations if you were starting from the ground up is something like this: # lvm pvscan <-- should see hdb as a PV in a VG # lvm vgscan # lvm lvscan <-- tells you the LV name that has the fs # lvm lvchange -a y /dev/$VGNAME/$LVNAME <-- activates the LV # mount /dev/$VGNAME/$LVNAME <mountpoint> -- Garrick Staples, GNU/Linux HPCC SysAdmin University of Southern California Please avoid sending me Word or PowerPoint attachments.

I will try Ubuntu :) Can you send more info on the partition schema for this HDD ? Antonio. -- +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ | Antonio S.

Were hda and hdb part of the same volume group? Or did hdb belong to a separate volume group? If hdb was in a separate volume group, you should be able to do a "vgscan" followed by "vgchange -a y". Those commands will scan your disks for any volume groups and activate them (see the man pages for details). Then mount the lvm that contains the samba partition and your data should be there. -Tim> > > Hi, > >I have a centos 4 box i use for a file server (nfs and samba).
