Package: login
Version: 1:4.4-4.1
Somehow /var/log/lastlog grew to a 110 TByte sparse file:
# ls -al /var/log/lastlog
-rw-rw-r-- 1 root utmp 110784817228 Feb 22 08:37 /var/log/lastlog
# du -h /var/log/lastlog
88K /var/log/lastlog
This affects rsync performance seriously, even when -S is used.
To reproduce the problem, please try
# time rsync -SHa /var/log/lastlog /dev/shm
real 4m0.621s
user 6m36.402s
sys 0m58.913s
Using our backup system as a destination for rsync I gave up waiting
after 15 minutes.
Do you think this could be improved?
UID_MAX is 60000, but our user database is freeipa on CentOS 7.6.
This might be related:
# getent passwd admin
admin:*:379400000:379400000:Administrator:/home/admin:/bin/bash
