Esx 4.0/4.1 might be not able to boot after reboot. It happens after update installation. Esx console says:
Filesystem type is ext2fs, partition type 0x83 uppermem 819200 kernel /vmlinuz ro root=UUID=ceadc074-b397-adcb-7b7604a8ab4a mem=800M quiet [Linux-bzImage, setup-0x1e00, size=0x179cdc] initrd /initrd.img Error 15: File not found Press any key to continue...
Quick look at usage space:
[root@esx8 ~]# df -h Filesystem Size Used Avail Use% Mounted on /dev/sda5 4.9G 1.8G 2.9G 38% / /dev/sda2 2.0G 97M 1.8G 6% /var/log /dev/cciss/c0d0p1 99M 91M 2.9M 97% /boot /dev/cciss/c0d0p2 4.9G 1.6G 3.1G 34% /esx3-installation /dev/cciss/c0d0p1 99M 91M 2.9M 97% /esx3-installation/boot /dev/cciss/c0d0p6 2.0G 114M 1.8G 7% /esx3-installation/var/log
There are still esx3 files remaining. This box has been upgraded from esx 3.x to esx 4.0. We can easily remove the old stuff with cleanup-esx3.
[root@esx8 ~]# cleanup-esx3 Are you sure you want to remove ESX v3 references and files? (y/N) y Cleanup of ESX v3 successful. Please reboot your system. [root@esx8 ~]# df -h Filesystem Size Used Avail Use% Mounted on /dev/sda5 4.9G 1.8G 2.9G 38% / /dev/sda2 2.0G 97M 1.8G 6% /var/log /dev/cciss/c0d0p1 99M 64M 30M 69% /boot /dev/cciss/c0d0p2 4.9G 1.6G 3.1G 34% /esx3-installation /dev/cciss/c0d0p1 99M 64M 30M 69% /esx3-installation/boot /dev/cciss/c0d0p6 2.0G 114M 1.8G 7% /esx3-installation/var/log [root@esx8 ~]#
Patrition table looks like that after the reboot.
[root@esx8 ~]# df -h Filesystem Size Used Avail Use% Mounted on /dev/sds5 4.9G 1.8G 2.9G 38% / /dev/sds2 2.0G 89M 1.8G 5% /var/log /dev/cciss/c0d0p1 99M 83M 12M 89% /boot
