We have had this happen on CentOS7 and Ubunto 14.04 LTS recently. Login then do sudo -i, enter a correct password at the password prompt only to get:
sudo: unable to open /var/log/sudo-io/seq: Read-only file system
We haven't tampered with 'seq' (per direction in reponse to a previous question). A reboot solves the problem.
egrep -v '^#|^$' /etc/sudoers on CentOS7 produces:
Defaults env_keep = "COLORS DISPLAY HOSTNAME HISTSIZE INPUTRC KDEDIR LS_COLORS"
Defaults env_keep += "MAIL PS1 PS2 QTDIR USERNAME LANG LC_ADDRESS LC_CTYPE"
Defaults env_keep += "LC_COLLATE LC_IDENTIFICATION LC_MEASUREMENT LC_MESSAGES"
Defaults env_keep += "LC_MONETARY LC_NAME LC_NUMERIC LC_PAPER LC_TELEPHONE"
Defaults env_keep += "LC_TIME LC_ALL LANGUAGE LINGUAS _XKB_CHARSET XAUTHORITY"
Defaults secure_path = /sbin:/bin:/usr/sbin:/usr/bin
root ALL=(ALL) ALL
%wheel ALL=(ALL) ALL
CentOS7 doesn't support MaxSeq, the highest directory under /var/log/sudo-io/00/00 is 4P. 'df -h' shows:
/dev/sda1 12G 98M 11G 1% /var/log
egrep -v '^#|^$' /etc/sudoers on Ubuntu 14.04 LTS produces:
root ALL=(ALL:ALL) ALL
%admin ALL=(ALL) ALL
%sudo ALL=(ALL:ALL) ALL
ALL ALL=NOPASSWD: /usr/bin/msmtp
'df -h' shows:
/dev/sdb1 9.8G 687M 8.6G 8% /var/log
