Possible stale mount?

I have a server running CentOS 7 and seems like there is a possible stale mount as df-Th does not return any response. The only solution (thus far) is to hard reboot the server and upon booting everything works fine for a week or so and the same issue is experienced. I have changed the OS drives wit...

Re: CentOS 7 Installation - No Local Disks detected

Looks like DMRAID was setup and hence the disks were not showing during installation. Performed the following and the issue is now fixed, DEVICE=/dev/sda # dd if=/dev/zero of=$DEVICE bs=512 seek=$(( $(blockdev --getsz $DEVICE) - 1024 )) count=1024 Did the same for /dev/sdb dmraid -r no raid disks

Re: CentOS 8 - Installation Error

Reverting to CentOS 7 which is having it's own issues. By the way the error occurred right at the start of installation so I didn't get to select mountpoint or specify username.

Re: A start job is running for dev-mapper-centos\x2droot.device

UPDATE: Looks like the BIOS defaulted on settings maybe due to a dead motherboard battery? However, changed the BOOT options to RAID and can boot into the OS fine now. Did not have to rebuild the server.
Can mark this topic as solved.

Re: A start job is running for dev-mapper-centos\x2droot.device

I seem to be at lost. I cant get to grub.cfg file as from emergency mode there is no /boot directory. And there is no fstab in /etc. There is just fstab.empty.

cat /proc/mdstat gives personalities:
unused: <none>

Re: A start job is running for dev-mapper-centos\x2droot.device

Thanks for that info Trevor. So is there no way for me to boot into the system currently and to backup data/config files from it. Rebuilding a server is not an issue but I am wearing thin on time tbh.

uhm, sorry Trevor, not sure what that means. Is the issue related to RAID?
