Re: Boot jfs in the bootmanager...

I have been testing eCS2.0-RC2. In particular I tried it on a JFS partition. At various milestones I made complete backups from a maintenance partition. After the latest backup, the partition would not boot. I booted from the maintenance partition and ran JFSCHK32 which said that the partition was clean. It still wouldn't boot.

To be more specific here is what happens when the eCS2.0RC2 installation on the JFS volume will not boot: The bootmanager screen appears and I select the JFS installation. The boot blob appears with a line at the bottom about the eCS JFS boot code. The eCS logo appears.

Following this one of two things has happened on each of many attempts:

1. The eCS logo stays on the screen and nothing happens. Ctrl-Alt-Del does nothing. Power down in necessary

2. The ACPI driver loads, followed by the message, "This driver is licensed only for use with e Com Station. The system is unable to operate your hard drive, the system is stopped." Again power down is necessary.

I tried booting from the maintenance partition again, running JFSCHK32, and then powering down and restarting instead of doing a warm boot with the same results.

I also tried booting from the install disk and running chkdsk from the maintenance console. That didn't help either.

I tried restoring several backups, starting with the newest but none of them would boot.

I then tried booting from the install disk, deleting the partition, then running the install up to the point of having created and formatted a new partition, then canceling the install and restoring a backup, with the same results.

Finally, I booted from the maintenance partition, formatted the partition as HPFS, restored the latest backup and ran sysinstx.com. That boots fine and everything works.

End of long story.

My question is how can one recover from a corrupted bootable JFS partition short of a complete reinstall?

Can anyone suggest anything I haven't tried?


How are you doing your backups? What backup program? Are you sure you're copying all the files with Hidden and System attributes? What about the EAs?
