I just noticed that the usual periodic email is not coming. I checked /var/ log/maillog and found that it's getting "Read-only filesystem" errors from maildrop several times a second.
The computer has two disks. /boot, swap, and / are on one; /boot1, /var, and / crypt are on the other. /boot1 and /crypt are read-write (I created a file on each, then deleted it). Only /var is read-only (and /var/crash and /var/tmp are null-mounts from /, which is on the other disk). It is somehow writing huge reams of "Read-only filesystem" errors to a read-only filesystem. Attached is the snippet of /var/log/messages when it put /var/ into read-only mode. What should I do? Pierre -- gau do li'i co'e kei do
