Bug#524199: linux-image-2.6.26-1-686: nfs unusable
Package: linux-image-2.6.26-1-686
Version: 2.6.26-13lenny2
Severity: important
Tags: patch
Overtime any system with NFS usage grinds to a crawl. While root or /usr on
NFS are most affected the same problem should affect other NFS usage. The
symptoms are extremely high system load, taking 20 minutes to open/close
applications, taking half a minute to create the menu on right click in KDE,
becoming unusable for 5 minutes while rebuilding menus in KDE, etc.
This is reported multiple times versus other packages elsewhere (mostly KDE
due to the idiotic way it builds its menus).
The reason seems to be: http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git&a=commitdiff&h=23918b03060f6e572168fdde1798a905679d2e06
discussed here: http://lkml.indiana.edu/hypermail/linux/kernel/0812.2/00418.html
On the positive side this made me find out that a whole bunch of programs
are coded with the left foot. This patch needs to be retrofitted
into the kernel to make it usable again for anyone using NFS and especially
diskless clients.
Otherwise, nfs in current kernel is unusable. After waiting for 30 minutes for tex to
update its map on an otherwise fast machine I downgraded all of my diskless clients to
2.6.18
