Dobry den Mam instalovany CentOS release 5.4 (Final). Serverova deska S3420GP s fake-raidem. V tom RAIDu na desce je udelany mirror. Pri instalaci to instalator nasel a pouzil jako /dev/sda. Divne je, ze v /dev/mapper je jenom soubor control
[root@mail dev]# ls -l /dev/mapper/
celkem 0
crw------- 1 root root 10, 63 bře 10 14:55 control
Vse se zdalo byt krasne a ciste dokud jsem neinstaloval updaty jadra /vse probehlo OK/ a jadra se zdaji byt nainstalovane
[root@mail dev]# ls -l /boot

pak jsem rebootoval.
Bootuje stale jadro ktere se nainstalovalo pri instalaci systemu (2.6.18-164.el5)
[root@mail dev]# uname -a

Takze jsem mrknul na bootmenu /boot/grub/menu.lst
[root@mail dev]# cat /boot/grub/menu.lst

vse vypadalo OK.
Proved jsem reboot a chtel vybrat jadro rucne v bootmenu GRUBu. Problem je ale v tom, ze v menu je pouze a jenom jadro CentOS (2.6.18-164.el5) .
Takze to je cely muj pribeh. Pokud mate nekdo nejaky napad, sem s nim.

Je to divny v dmesg vidim toto:
device-mapper: multipath: version 1.0.5 loaded

kjournald starting. Commit interval 5 seconds
EXT3 FS on sda9, internal journal

ale v systemu:
[root@mail log]# mount
/dev/sda1 on / type ext3 (rw)
proc on /proc type proc (rw)
sysfs on /sys type sysfs (rw)
devpts on /dev/pts type devpts (rw,gid=5,mode=620)
/dev/sda9 on /home type ext3 (rw)
/dev/sda8 on /tmp type ext3 (rw)
/dev/sda7 on /opt type ext3 (rw)
/dev/sda6 on /usr type ext3 (rw)
/dev/sda5 on /zal type ext3 (rw)
/dev/sda3 on /var type ext3 (rw)
tmpfs on /dev/shm type tmpfs (rw)
none on /proc/sys/fs/binfmt_misc type binfmt_misc (rw)
takze ted nevim z ceho je namontovany / - korenovy FS.
Takze to vypada ze je namontovany /dev/sdb1 ale hlasi to /dev/sda1 co s tim ?
