Re: [CentOS] which kernel do people use?
If you want SSD + MDRAID you need to use a 3.8+ kernel to have TRIM. The speed difference between the stock 2.6.32 - 3.10 kernel with SSD + MDRAID is insane.

Re: [CentOS] 11TB ext4 filesystem - filesystem alternatives?
You should upgrade to a newer kernel - there are lots of improvements to ext4 since the rhel5 kernel... rhel/centos 6 is a start but if you don't need rhel/centos you could try Ubuntu 12.04 to see how the 3.2.x kernel handles it. cheers On 27 September 2012 10:47, joel billy jbilly2...@gmail.com wrote: On 9/27/12, Fernando Cassia fcas...@gmail.com wrote: So, again, what´dya mean by less supported?.

[CentOS] Centos 5.7 - bridging firewall crash (only since the update) - dmesg output included - Trying to vfree() nonexistent vm area (ffffffff885d9000) ....
Hi. We have several Centos 5 firewalls in our company - they are all in bridging mode. We updated them to the latest Centos 5.x last night. 4 hours later there was a crash.. (previously it had never crashed - and had been running for at least 1.5 yrs) The crash occurred when someone added a rule, after rebooting it was fine - the thing is it can't have been a bad rule as the first thing the server does is load the firewall (same) rules..
