[1.] One line summary of the problem:
sometimes when I boot up my computer the root device /dev/md1 is
mounted read-only.
[2.] Full description of the problem/report:
sometimes when I boot up my computer the root device /dev/md1 is
mounted read-only. it has until now never occured wih the other raid
device /dev/md0 (on which I have a lvm installed). since the computer
can't write to /var/log when the bug occures it prints out the error
message in the virtual terminals:
"EXT3-fs error (device md1) in start_transaction: Readonly filesystem"
and sometimes he writes:
"EXT3-fs error (device md1) in ext3_delete_inode: Readonly filesystem"
the mount command says that /dev/md1 is mountes read write (option rw).
what I do about it is I reboot the system. then normaly the root device
is mounted rw as it should.
[3.] Keywords (i.e., modules, networking, kernel): ext3, boot, unstable
kernel, software raid.
[4.] Kernel version (from /proc/version):
