comment Can “enterprise” drives be safely replaced by near/midline in some situations?
Seagate offers 5 year warranties on both their 7200rpm and 10k sas drives. Warranty length is more likely to be a pricing decision than an expected lifetime decision. I would expect either drive to outlast the warranty.

comment Can “enterprise” drives be safely replaced by near/midline in some situations?
I did a quick price check on current seagate 2.5" drives. the 1TB drive is ~$200, the 900GB drive ~$300. The 900GB uses about 2.5w more "average operating power" also. ... I didn't mean to suggest that the server or drive would overheat - clearly unlikely. But all things being equal, there is less stress on a 7200rpm drive than on a 10k drive; that may lead to longer life. Regardless, I'm willing to concede your point - the faster drive is slightly less risk (likely to perform, not much more likely to fail). Whether that is worth the additional expense is for the reader to decide.

In general this answer is great. But like with anything else, "it depends." In the example of a 900GB 10k vs 1TB 7200 disk, the 1TB disk will run cooler and therefore perhaps last longer, and will be less expensive. If you don't need the additional performance, then it's a waste of money, both the original capital cost and operations. For one server, it doesn't matter much. For 10, it starts to add up.

comment CentOS - Raid Speed Below Single Disk
No surprise that software RAID1 is slow on writes. It has to write the data twice. It is a surprise that "RAID" 0 is the same speed as a single disk - i'd generally expect that to be roughly twice the speed. Seems likely you are getting a bottleneck in the chipset's SATA (or its linux drivers). You might try adding a PCIe SATA controller and moving one of the disks to that. Or, as womble suggests, for best performance buy a hardware raid card.

comment Nagios check_ssh returns usage information instead of status
You can turn on debug logging in nagios, which will show you the command that is being run. mail-archive.com/nagios-users@lists.sourceforge.net/… Probably, you need to adjust your command definition.

comment Xen - reduce resources/hardware limitation?
You want a lot of premium features and you want to pay a tiny amount for the service. Good luck with that.

comment logrotating files in a directories and its subdirectories
Not really directly relevant but probably useful to someone. the -f option tells logrotate to "force run". a bare word at the end of the command is a config file to use instead of the default. so logrotate -f /some/config means run with that config file, and always run even if the config file says it's not time to run yet. To my untrained eyes, and to my predecessor who put in a cron job with that, it seemed like -f was just specifying the config file. Quite confusing.
