Well, there is one problem I vaguely remember that I don't think has been=20 addressed, I think it was one of those lets-put-it-off-till-v4 things. It w= as=20 the fact that there are a limited number of inodes (or keys, or whatever yo= u=20 call a unique file), and no way of knowing how many you have left until you= r=20 =46S will suddenly, one day refuse to create another file. (For comparison, ext3 seems to support not only telling you how many inodes= =20 you have left, but tuning that on the fly.) But, I haven't run into that, and the only problem I've had lately has been= =20 Reiser4 losing data, and crashing occasionally. I switched most of my data= =20 off of Reiser4 and onto XFS for that reason. I've also been using ext3 in=20 some places, and Reiser3 in others (one place in particular where space is= =20 limited, but I will have tons of small files). I later learned that XFS does out-of-order writes by default, making me thi= nk=20 I should give up and invest in UPS hardware. But, switching away from Reise= r4=20 means I no longer see random files (including stuff in, for example, /sbin,= =20 that I hadn't touched in months) go up in smoke. Ordinarily I like to help debug things, but not at the risk of my data. May= be=20 I'll try again later, and see if I can reproduce it in a VM or somewhere=20 safe... I do still follow the list, though, in case something interesting happens. = It=20 was fun while it lasted! --nextPart3955226.Ff2qMm1UZX Content-Type: application/pgp-signature -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.6 (GNU/Linux) iQIVAwUARl17RXgHNmZLgCUhAQJByw//XuSJzsbzU0TvNLfIl6GQe3IXX5Qp8mnn mzYFyk9EEV0eNaSQdtUFOEATlvVk+n5+Sv5h0glAHyHvAfLFowj+HJmNCxu4xr9v FqAYq7hDojlqE1HoRTII24cy1taPuUOMggvSgm0ph4HRJ31LfEUTMVtVNaPAvl6X QbBdwS+sjt3rzW3q4Z7s2KcXH8Epm6pVS0Fg9m4Ujk3JNvVwyeDam6RvQQxCgu2L XbBS7fptwoS7rgr+lP6T/kvXg+bS7UzZTknrTeUMspdI43m7TD2P6FzB3bL4yEAr q8gKcAIXfhv/N9DyoNbEHckVQeJzMI9LmEYwZe4X8IB8C4ZZlJ/1odzflmCCISy6 /7F9FsKfkGW6NnUGk1FPjkV+vTb6i0zoNJE4j5L0lsTUdGvSx9QP5aTecyT46u2x 9/Wy3q02SjZUNxdEB9qiR2D27O0r25Gt/wm+t7JA2pCD9ioWmtk0U05/APZJZh45 6LArniYYgQsqVfzRAzTapGxQ5BwjhbJq1DbVRBE/BII6rSscOxA9cksJUL1XqLPV boHn0CucsBZ6yJs9OcO9SZvcLRaw4uPk5xVlpG+cl2lYQIZ6c+ftQ8eTa/8wOyX4 ETrYwuhjB92ojUc2OJHLp47KfyCIAjsqAPvamqAkVKIrW1yWN1SuitwHojoi7o9e DYNUj1+GaJA= =/oFX -----END PGP SIGNATURE----- --nextPart3955226.Ff2qMm1UZX--
