Какую файловую систему лучше взять?
Отпишитесь у кого опыт есть. Я думаю XFS но не знаю почему я так думаю. По крайней мере видел в доках что ее предлагают взять.

Каждая ФС имеет свой конёк: какая-то лучше с большими файлами работает, какая-то с килограммом мелких файлов справляется на ура, у какой-то повышенная отказоустойчивость, какая-то для кластерных дел итд. Но сочетающей в себе все перечисленные плюсы пока не придумали 
А тебе для чего?
В ядре же есть, вроде, пара кластерных ФС (GFS2 от RedHat'а и OCFS2 от оракла) и обе описаны хорошо - не хочешь попробовать? Сама не пробовала ни ту, ни другую.

таки взял GFS. на drbd.org там примерно расписано как ее настроить. пока не знаю как правильно составлять /etc/cluster/cluster.conf
пс: вроде тут не плохо описано - http://gcharriere.com/blog/?tag=gfs

мля. застрял с построением Файл Кластера на CentOS 5.x. хз что делать. компилировать пакеты как написано тут (http://gfs.wikidev.net/Installation) нужно избежать. но по ходу (https://bugzilla.redhat.com/show_bug.cgi?id=217724) как то не получается, хотя проблема у меня немого другая.
