I too have a server running with a LVM2 setup. My advice is put a 2G / on a real partition not an LVM2 partition. It makes maintenance and recovery much easier in case of trouble. Everything else can go onto an LVM2 volume such as /var /user /home /tmp /mnt/vmware swap ( mostly because my server almost never has to swap ) I can then resize and reallocate space. The file systems are all reiserfs. (I am unlucky when it comes to XFS and ext3, but they should work too.) I am not sure if XFS has an online resizer. If you can, use evms as as an admin tool for your volumes. It has a very user-friendly interface in "evmsn" A couple of months down the road you can look at your diskspace utilization and resize or shrink a few partitions. The only fixed partitions would be / and maybe a separate /boot -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.5 (GNU/Linux) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iQEVAwUBRUmrxMvODX+91FTAAQLsCgf9EELhR7PfGGevMOnldi70TVsYNtPdmxQd RTGpuBVgUqZuNXoRSIhBb3MgWIMglpSkOG7RCMrcGIHeHXlkogwF7RDIvX7Q3n/a gjwRrRHUX+6DSeAaX627xt7PFcLu/hwLFfOh01czvaQy3sbTwj5lLkD7TBnvGfKm ePKP0ACuCM/CNBApt0eQasb9X2wtJOHQ7oKnYqUZHpLi368vBOzVEE8JTV+gmiOL RzmdqBJFCtoTP9WZJhMjq+CsOYAfOUUCLxoON+8JK0AJ5l2RUez+QXmVGNA7rWcq 2hSJ3MvOs8lc4C+KLtMfLNtNvKgAz8mrNc3GlRCM0HvfhA65aAg6ig== =KCO5 -----END PGP SIGNATURE----- _______________________________________________ arch mailing list arch@archlinux.org http://www.archlinux.org/mailman/listinfo/arch
