Hi mark I was looking to just move/grow the one mount point only, short term I will create specific mount points with a new Mod 9 behind it, the next install I will go LVM from the start.

If I replace all of the occurrences of "mount point(s)" with "filesystem(s)" is makes a little more sense. You mention MOD-9s, so its fair to assume that you have a filesystem that has now reached 6.8GB and is maxed out. So you need to create at least 2 new PVs each of 1 by 3390-9. Add those PVs to a new VG. Create an LV of > 6.8GB in the new VG. Remember to add any new DASD device numbers to your zipl.conf (make a backup first) and run zipl. Now you have a choice. Create a new filsystem in the LV and play various filesystem copy methods using "cp" or "tar", or directly copy the whole filesystem using "dd". For "dd", first unmount the existing filesystem. (or at least remount it RO using "mount -oremount,ro /dev/dasdx1".) (It would probably be a good idea to run e2fsck on it at this point.) Use "dd" to copy the /dev/dasdx1 to /dev/vgname/lvname. "dd if=/dev/dasdx1 of=/dev/vgname/lvname" Then run resize2fs on /dev/vgname/lvname to grow your filsystem into the new and larger LV. (Again running e2fsck on the new LV would be a good idea) Remember to update your /etc/fstab (make a backup first) with the new LV /dev/vgname/lvname in place of your old filesystem /dev/dasdx1. "mount /dev/vgname/lvname" should now mount it in place of the old filsystem. If the new filesystem verifies OK - you be the judge of that. Then you can recycle the old MOD-9. If there are problems then use the backup copy of your /etc/fstab to remount the old filesystem. There are many ways to skin a cat, the above is but one of them ;-) mark ---------------------------------------------------------------------- For LINUX-390 subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: INFO LINUX-390 or visit http://www.marist.edu/htbin/wlvindex?LINUX-390 _____________________________________________________________________________________________________________________________________ Standard Bank email Disclaimer and confidentiality note This e-mail, its attachments and any rights attaching hereto are, unless the content clearly indicates otherwise, the property of Standard Bank Group Limited and its subsidiaries.
