/boot doesn't appear to be full, there appear to be 25.2 megabytes free with 20.1 available.
another curious thing I just noticed is this: the list of kernels available
at boot time (in the actual grub menu shown at boot) IS NOT THE SAME LIST
THAT APPEARS IN GRUB.CONF. in the boot-time menu, the kernel it boots is
the most recent one shown, and there are other older ones that do not
appear in grub.conf. while in grub.conf there are several newer ones that
do not appear on the boot-time grub menu.
most strange.
BTW, this is a raid-1 array using linux software raid, with two matching
drives. Is there possibly some way the two drives could have gotten out
of sync such that whichever one is the actual boot device has invalid
info in /boot?
and while thinking along those lines, I see a number of mails in root's
mailbox from "md" notifying us of a degraded array. these all appear to have
happened, AFAICT, at system boot, over the last several months.
also, /var/log/messages contains a bunch of stuff like the below, also
apparently at system boot, and I don't really know what it means, though
the lines mentining a device being "kicked out" seem ominous:
