Like right now if I do a df I don't see the disk. But I swear if I check back in and run df again, I see.
/dev/sda1 235326136 14150544 209221628 7% /mnt/device/57
I'm having problem rebooting. When this problem happens, i did notice like 20 process of mdadm running. Might be related to disappearing sda1. The only way I can reboot at that point is to hit power button or send command
echo b > /proc/sysrq-trigger
Thanks in advance.
