It looks like my x86_64 router loses power once in a while, and mounts a few points as ro:
Code: Select all
root@Gargoyle:/etc/config# mount
/dev/root on / type ext4 (ro,noatime)
proc on /proc type proc (rw,nosuid,nodev,noexec,noatime)
sysfs on /sys type sysfs (rw,nosuid,nodev,noexec,noatime)
tmpfs on /tmp type tmpfs (rw,nosuid,nodev,noatime)
/dev/sda1 on /boot type ext4 (rw,noatime)
/dev/sda1 on /boot type ext4 (rw,noatime)
tmpfs on /dev type tmpfs (rw,nosuid,relatime,size=512k,mode=755)
devpts on /dev/pts type devpts (rw,nosuid,noexec,relatime,mode=600,ptmxmode=000)
debugfs on /sys/kernel/debug type debugfs (rw,noatime)
/dev/sda2 on /tmp/usb_mount/3a893016-02 type ext4 (ro,noatime)
Code: Select all
root@Gargoyle:/etc/config# df -h

Secondary questions are:
* How do I prevent this from happening again if I lose power? Is there a config option to just always mount as rw?
* Is this a result of going with ext4 instead of squashfs? I've never had this issue on my old Buffalos, Netgears, etc.
Thanks in advance!
