Had been using Fedora Core 23 for a few months and then turned on the computer, entered my boot password, and instead of getting the user login screen as usual I got the following message after it had booted:
Generating "/run/initramfs/rdsosreport.txt"
Entering emergency mode
Exit the shell to continue
Type "journalctl" to view system logs.
:/#
I tried looking at the report and there were a number of lines in red, errors such as:
"Buffer error I/O dw dm-1"
"error {UNC}"
"Read FPDMA Queued"
"fsck failed error 4"
"res (long MAC address looking numbers, then) media error F"
"Blk update request I/O error dev/sda"
Towards the end of the file:
"Dependency failed for /sysroot"
"Dependency failed for INITRD root file system"
Not in exact order.
I tried running "fsck" ("/sbin/fsck") but it didn't do anything.
Anyone out there know if I'm just totally hosed and need to reinstall from scratch and hope I have backups? Or is there any way to fix the LVM config or whatever else might be causing this? S.O.S.
Thank you for any and all help...
You may want to boot into rescue mode and repair the disks.
