I recently updated two 64-bit CentOS 5.3 systems via yum update.
- One system had two physical SATA hard drives - drive 0 was Windows
XP w/SP3 w/NTFS, drive 1 was CentOS;
- The other system had two physical SATA hard drives, configured via a
hardware mirror of RAID 1 (mirroring)
After the latest yum update, grub on both systems failed me, dropping
to the grub prompt.
For the dual-boot system, I ended up reformatting and reinstalling
Windows on drive 0. The CentOS was not touched. That system is
fine now.
For the RAID CentOS-only system, I experimented with removing one
drive from the mirror and CentOS booted as though it was reboot after
a fresh install, though there were some traces that something else
(like an upgrade) was mixed in, but didn't work right. I ended up
deleting the hardware RAID and removed a drive. That system works
fine now.
Has anyone else experienced grub problems with more than one drive
installed from a recent yum update?
I will not perform an update on any other multi-drive systems,
including servers, until I know things are fixed.
Thanks for any insights.
Scott
