Так как обещал проверить сообщаю: в Debian Etch работает.
Сначала про систему:
home:~# uname -a
Linux home 2.6.18-4-686 #1 SMP Wed Apr 18 09:55:10 UTC 2007 i686 GNU/Linux
home:~# dpkg -l 'jfs*' | grep ii
ii jfsutils 1.1.11-1 utilities for managing the JFS filesystem
home:~# dpkg -l 'lvm*' | grep ii
ii lvm-common 1.5.20 The Logical Volume Manager for Linux (common
ii lvm2 2.02.06-4 The Linux Logical Volume Manager
Теперь проверю:

Я говорил что не работало без указания параметра у resize. Проверю позже т.к. то
было на amd64 и ядро там xen-vserver. Кроме того ядро уже обновлялось в
дистрибутиве.
Проверю и там только попозже.
P.S. В ядре точно есть патчи для JFS.
P.P.S. Если надо что-то посмотреть/протестировать - говорите куда копать.
Небольшая заметка. Если раздел забит на 97% то kernel oops ловится стабильно на любой системе. reassign Хорошо бы: - проверить на 2.6.32; - если да, то в апстрим. ovz-smp в сизифе опять нет. |
