Hello list, I Booted nicely into FC4 / KDE, and was trying to set ALSA sound parameters to make the 6 channels work correctly (they were going here ,there and no-where) then I saw this 1. while opening konsole and error appeared (twice) fgrep: error while lkoading sharedlibrary, /lib/libpcre.so.0: cannot read file data: invalid argument fgrep: error while lkoading sharedlibrary, /lib/libpcre.so.0: cannot read file data: invalid argument but allowed to work in konsole 2. then there was a full lockup, no mouse, no keboard response, therefore no virtual console also. I had to press reset button. 3. Then FC4 refused to boot; boot process starts and comes upto a stage and hangs following is as best I could note as seen on screen quote ... ... INIT: Version 2.85 booting fgrep: error while lkoading sharedlibrary, /lib/libpcre.so.0: cannot read file data: invalid argument fgrep: error while lkoading sharedlibrary, /lib/libpcre.so.0: cannot read file data: invalid argument setting defaull font (latarcyrheb-sun16): OK Welcome to fgrep: error while lkoading sharedlibrary, /lib/libpcre.so.0: cannot read file data: invalid argument fgrep: error while lkoading sharedlibrary, /lib/libpcre.so.0: cannot read file data: invalid argument ... ... ... Initializing hardware ... Unquote here it hangs like ctrl-alt-del not working but numlok capsloak working, onlyway to proceed is reset button Computer is working as I writing this via knoppix....CD I have the root on /dev/sda3 (ext3) partition and rest of linux on /dev/sda4 LVM2 # sfdisk -l Disk /dev/sda: 9733 cylinders, 255 heads, 63 sectors/track Units = cylinders of 8225280 bytes, blocks of 1024 bytes, counting from 0 Device Boot Start End #cyls #blocks Id System /dev/sda1 * 0+ 1215 1216- 9767488+ 7 HPFS/NTFS /dev/sda2 1216 7820 6605 53054662+ f W95 Ext'd (LBA) /dev/sda3 7821 7836 16 128520 83 Linux /dev/sda4 7837 9732 1896 15229620 8e Linux LVM /dev/sda5 1216+ 2593 1378- 11068753+ 7 HPFS/NTFS /dev/sda6 2594+ 4505 1912- 15358108+ b W95 FAT32 /dev/sda7 4506+ 7820 3315- 26627706 b W95 FAT32 ------------------------------------------------------------------------ So dear friends help me recover the LVM /home partition Please tell me how 1. to repair through the rescue disk.. 2. to mount LVM in this case I suspect that as soon as a request to access /dev/sda4 is made the error appears; I may be inaccurate. -- Anil Kumar Shrama
