Re: [CentOS] /var/log/lastlog on x86_64

thanks for your replies, I will try this one, since the server is not in a production state. What would happen if it was... a simple grep eating 2 GB of RAM.... David Johnston wrote:

4. Remove the nfs-utils package, remove /var/log/lastlog, and recreate

it. This should make lastlog much smaller, unless you have a lot of users on your system.

2. Change the format of lastlog so it doesn't use a sparse file. This

isn't trivial, but I think it's probably the best solution in the long run (unless #1 happens).

This is painful for most ways of backing up and cloning systems too. How about gdbm format as something that would work with miminal changes?

I dont get it. lastlog is in dbm format and if it is converted to gdbm it wont't be a sparse file anymore ?
