There are a number of possibilities that would be perfectly normal. 1. If the two 73G drives are mirrored, you'd see a single 72G volume, not two volumes and not a 144G volume. >> the two 73G drives are NOT mirrored 2. It's normal not to allocate all the space at once, so later you can grow the filesystems as needed. E.g. # vgdisplay --- Volume group --- VG Name NeptuneVG System ID Format lvm2 Metadata Areas 1 Metadata Sequence No 16 VG Access read/write VG Status resizable MAX LV 0 Cur LV 9 Open LV 9 Max PV 0 Cur PV 1 Act PV 1 VG Size 68.28 GB PE Size 32.00 MB Total PE 2185 Alloc PE / Size 881 / 27.53 GB Free PE / Size 1304 / 40.75 GB VG UUID Naut63-Nfjh-Hl12-Ci1F-Vyj2-WqeJ-7HI0Ba Notice the line "Free PE / Size 1304 / 40.75 GB". On this system, there are currently 40.75 GB of unallocated space in the LVM volume group, which can be added to any of the filesystems as needed. If /var was running low and I wanted to increase it by 2G, # lvextend --size +1G /dev/NeptuneVG/var # ext2online /dev/NeptuneVG/var The "lvextend" adds more space to the logical volume that /var uses, and the "ext2online" expands teh ext3 filesystem to use the additional space. -- John Abreau IT Manager Zuken USA 238 Littleton Rd., Suite 100 Westford, MA 01886 T: 978-392-1777 F: 978-692-4725 M: 978-764-8934 E: John.Abreau at zuken.com W: www.zuken.com "The information in this e-mail and in any attachments is confidential and intended solely for the attention and use of the named addressee(s).
