Anyone running LVM and have comments about the amount of overhead it uses? Here's my setup: Debian woody 2.4.27 kernel w/LVM compiled in. Box his attached to a jetstor filer that hands out a chunk of disks as a single scsi target. The jetstor is doing RAID-5. I know little else about the filer, someone else admins' it. dmesg shows: SCSI device sda: 627932160 512-byte hdwr sectors (321501 MB) If is just run fdisk, create one partition and then run "mke2fs -j -m1 /dev/sda1" I get: Filesystem 1k-blocks Used Available Use% Mounted on /dev/sda1 309030804 32828 305858396 1% /jetstor If I setup the disk via LVM (pvcreate, vgcreate, lvcreate) I get: Filesystem 1k-blocks Used Available Use% Mounted on /dev/vg01/lv00 263191620 32828 260484924 1% /jetstor I get the same results whether I use the entire disk "/dev/sda" or create a single partition of type "Linux LVM" (8e). Any idea why LVM takes about 45 GB of overhead? -- scot _______________________________________________ TCLUG Mailing List - Minneapolis/St. Paul, Minnesota Help beta test TCLUG's potential new home: http://plone.mn-linux.org Got pictures for TCLUG?
