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.
