CentOS 7 install on one RAID 1
by m.roth＠5-cent.us 26 Jan '17

26 Jan '17

Hi, folks, I'm building a new box, and I want three partitions - /boot, /, and swap, on *one* RAID 1, not three separate partitions. Other than <alt-f2> mdadm..., *is* there any way in the graphical installer to do this? All I see is a way to make three separate partitions. Pointers to links happily accepted. mark, back to googling

SELinux file permissions

Hi, I'm trying to grant dovecot the ability to manage its socket within the postfix spool directory. I have added the below to file_contexts.local : /var/spool/postfix/private/dovecot-auth system_u:system_r:dovecot_t:s0 However, running "restorecon -v /var/spool/postfix/private/dovecot-auth" gives me the following error : restorecon: lstat(/var/spool/postfix/private/dovecot-auth) failed: No such file or directory I cannot create the socket file in advance, because dovecot manages it, and if you "touch" the file, dovecot complains. Where am I going wrong ? Thanks ! Tim

CentOS 7 and Areca ARC-1883I SAS controller: JBOD or not to JBOD?
by Peter Peltonen 22 Jan '17

22 Jan '17

Hi, Does anyone have experiences about ARC-1883I SAS controller with CentOS7? I am planning to have RAID1 setup and I am wondering if I should use the controller's RAID functionality which has 2GB cache or should I go with JBOD + Linux software RAID? The disks I am going to use are 6TB Seagate Enterprise ST6000NM0034 7200rpm SAS/12Gbit 128 MB If hardware RAID is preferred, the controller's cache could be updated to 4GB and I wonder how much performance gain this would give me? Thanks! Peter

Restricting mirrors off a repo
by Mauricio Tavares 21 Jan '17

21 Jan '17

What is the best way to specify which mirrors off a repository you want to use? Have a host with rather restricted egress rules and want to allow it to reach a couple of mirrors for each repo it needs. And, yes, I am not ready to mirror them locally.
