You can put a filesystem on a RAID, of course. LVM is not really a solution, for several reasons. For example, it seems as though it's actually possible to have an entire partition fragmented in the same way that a single file can be, and there's no way to fix that. It also requires the user to change things. Now, why would I use separate filesystems in the first place? Two reasons: performance and security. Right now, it's a lot easier to have /var be a certain sized partition rather than trying to enforce disk quotas. It also improves performance if we know that quickly moving data like that in /tmp is separated from slowly moving data like that in /usr. However, I think both of these problems could be solved to the point where an intelligent filesystem would beat an intelligent admin on partitioning any time. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.2.3 (GNU/Linux) Comment: Using GnuPG with Thunderbird - http://enigmail.mozdev.org iQIVAwUBP9CPcwisZLIF6uqOAQJePA//UIo+NjWW6AwLSNpanthF+kggKGQ5R/ha GYim57s3BRCKOl1JSSpopCsM2jgKQvSqUzdLOJJX7BB8G1YNoGNB5/RAHaW8EmEp bJ3rZro+ki2lkA4zAMiXP5f1Sfk3McjFA07C0ZBVOy1pC1oZ1max7YvLn/qIdJPe JuDeWRadNYly6Tcjykehio/Lsd5FJI52TBetZZ/SMuY6ib3EB8JPLrjjBpAxcXFZ n9vZduC7rPEsS5YWtdWtUebR6uPZg4eYNUc2er1GG3Z0beMCwKtB6lM7/NxBd0Pt JG+JekxKxTQxZOAaL88oOJ8wpiQMh0/BP8yHMimnOY7YwPKJYjblGl5Od9lngGoY 0dLEVjmjvPjUB4qyV8m1xxI1DGWbXOmjxV8zfZzYgvj6C1BqGArzc1pKlic0CrS3 ZgvoddjzEZlSSfmndlzh9JokIxsI63vLxA6qUkLYVn0NCKKq/XecmKlhHGCOPEWD t0FLmqjYl3p2rSrpUrcCiZXOOhjCKo5ae2NHlfT6aDJDR930i1QFROYZdSWi8L7y /nqnlKdQOQuP7dI+cndZTAf4WvHS095TE/rsveKlkMhVpo+V4UbWse6q5xTrzU3X CYJkggpmzhwiRF+GEscnCcY2uCIxn8cteShpWmlYjJmZZ1AofaFC8b/ChKutrPJP SuxuINXgjhE= =tsHB -----END PGP SIGNATURE-----
