using /cruc/etc/mountinfo.rc-ca-ostest293 got these params: fstype=reiserfs, logdir=/cruc/runs/6455/test_output, mountdev=/dev/cciss/c0d0p4, mountpoint=/tester mountoptions=data=journal, fsblocksize=4096, iosched= umount: /dev/cciss/c0d0p4: not mounted mkfs.reiserfs 3.6.19 (2003 www.namesys.com) A pair of credits: Yury Umanets (aka Umka) developed libreiser4, userspace plugins, and all userspace tools (reiser4progs) except of fsck. Nikita Danilov wrote most of the core balancing code, plugin infrastructure, and directory code. He steadily worked long hours, and is the reason so much of the Reiser4 plugin infrastructure is well abstracted in its details. The carry function, and the use of non-recursive balancing, are his idea. FATAL: Module reiserfs not found. mount: unknown filesystem type 'reiserfs' error: mount failed, sts=32
