pam_sss fails to close cache files
by Anand Buddhdev 03 Jun '16

03 Jun '16

Dear folks, After updating some of our servers to CentOS 6.8, we've noticed that the ones using pam_sss.so for authentication, appear to be suffering from a leak of sorts. On these systems, the /var partition is running out of disk space, and we eventually noticed that it's because of deleted, but still open files like these: httpd 1081 apache 8r REG 253,2 6406312 6199 /var/lib/sss/mc/group (deleted) sshd 1609 root 3r REG 253,2 8406312 431 /var/lib/sss/mc/passwd (deleted) mysqld 2018 mysql 4r REG 253,2 10406312 436 /var/lib/sss/mc/initgroups (deleted) Each time any process uses pam in some way, it's opening these cache files in /var/lib/sss/mc, but not closing them, and they're accumulating. The reason they're accumulating is that the initgroups, group and password file are frequently refreshed (by sssd), and so each open() call to them looks at a new file. We traced the sshd process, and noticed this: open("/var/lib/sss/mc/passwd", O_RDONLY|O_CLOEXEC) = 3 But there is no matching "close(3)" call anywhere (all other files opened have a matching close() system call). Has anyone else seen this issue, and does anyone know a quick solution to this? Regards, Anand

Minimum RAM requirement for CentOS 6.x graphic installer?
by Nicolas Kovacs 02 Jun '16

02 Jun '16

Hi, The title says it all. What's the minimum RAM requirement for the CentOS 6.x graphic installer? In our public libraries we have some old hardware running CentOS 5, and I wonder if some of these machines can be upgraded to CentOS 6. Unfortunately RHEL 5.x' nifty text mode installer got seriously crippled with version 6.x.

Some of us, well at least 1, have written a simple PHP programme, run on Apache, which instantly searches the current log and the archived logs for anything in the logs. Tracing items in Exim could not be quicker or easier - all done from the comfort of a web page with no terminal CLI or GREP insight. -- Regards, Paul. England, EU.

I think that if you feed the install a kickstart file, it will install in accordance with what you told it, but that does mean you have to spend some time figuring out what to put in your kickstart first. This would also give you some consistency between systems. Or you could let the 6.x "text installer" install it's minimal system, and then comeback and yum install everything else afterwards. fewer choices to make, but you get to live with RH's ideas of sane partition sizes. Another option for installing on smaller machines is to use the live disk[1] and a few tweaks[2] to do the install. However it will mean some hand holding on each machine to make it work, but I have done it and been reasonably happy with the resulting system. Note on a really small system (512MB or smaller), the use of zram (with the normal centos kernel, and swappiness~99), or zswap (with the elrepo kernel-ml) will make the system operate a lot better. It is too bad the live disks to not enable zram while booting when they don't find a linux swap part.

Centos 7 and Software Raid Minimal Install
by Matt 01 Jun '16

01 Jun '16

I am trying to install Centos 7 on a couple 4TB drives with software raid. In the Supermicro bios I set UEFI/BIOS boot mode to legacy. I am using the Centos 7 minimal install ISO flashed to a USB thumb drive. So I do custom drive layout something like this using sda and sdb. Create /boot as 512 MB XFS raid1 array. Create SWAP as 32 GB SWAP raid1 array. Create / on 3.xxx TB XFS raid1 array. I then get error. "Your BIOS-based system needs a special partition to boot from a GPT disk label. To countinue, please create a 1MiB 'biosboot' type partition." I cannot seem to create the biosboot partition so it is mirrored to both drives for redundancy. Any ideas how to do this? I want everything mirrored to both drives.
