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...
