[CentOS] Minimum RAM requirement for CentOS 6.x graphic installer?
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.

Re: [CentOS] Slow RAID Check/high %iowait during check after updgrade from CentOS 6.5 -> CentOS 7.2
I did some additional testing - I stopped Kafka on the host, and kicked off a disk check, and it ran at the expected speed overnight. I started kafka this morning, and the raid check's speed immediately dropped down to ~2000K/Sec. I then enabled the write-back cache on the drives (hdparm -W1 /dev/sd*). The raid check is now running between 10K/Sec and 20K/Sec, and has been for several hours (it fluctuates, but seems to stay within that range). Write-back cache is NOT enabled for the drives on the hosts we haven't upgraded yet, but the speeds are similar (I kicked off a raid check on one of our CentOS 6 hosts as well, the window seems to be 15 - 20K/Sec on that host).
