comment replacing 3 drives out of 8 in a server
@Pico the document I linked to provides the relevant information on the various RAID levels an their strengths/weaknesses. Which you choose to use is a business decision. I don't know what a blinking light on a Dell R510 (drive) means but I do know that now you have replaced 3 drives your RAID 5 is dead and will need to be recreated and the data recovered from a backup.

@Sirex, Thank you for taking the time to actually read my nomination. It's a pity that so few appear to have done so.

So, you haven't been active here for a long time. You don't participate in meta, cast flags, have many notable badges and your voting is appalling. How is this a good basis for being a moderator?

comment Apache unable to write on 2777 folder
If you had provided the relevant information from your logs, in particular the audit log and error_log we may have been able to help you solve this correctly. Disabling SELinux may be expedient but it is almost never the correct solution.

comment Apache unable to write on 2777 folder
Instead of disabling SElinux - why don't you spend bit of time learning it and fix the problem correctly ? Disabling SElinux is (almost never) the correct answer.
