Local Yum Repository Setup

Oracle has updated the instructions on how to setup a local yum repository for Oracle's Unbreakable Linux program. It's a bit shorter, clearer and the channels are better explained than before.
However, if you want have a yum repo mirror that can also utilize ISO images as well as a set of custom RPMs, not normally in the repository, be sure to check out DAG's mrepo instead. Using mrepo, you can have a yum repo, a dir with local, custom RPMs for specific apps, as well as plain straight ISO images.

Update: their yum population script was updated again late December.

See screenshot on the right.

Here is what I did: Use -t to TEST ANY LVM action first! We are going to release 1 TB from LVM. The Volume group was extended with 1 TB storage to serve as a cheap NFS/CIFS file server when setting up our data center. It is now deprecated and replaced by a NAS so it's no longer needed. 1) check LVM; note the four 256 GB LUNs [root@server ~]# pvscan -v Wiping cache of LVM-capable devices Wiping internal VG cache Walking through all physical volumes PV /dev/sdb1 VG vgdata lvm2 [50.00 GB / 0 free] PV /dev/sdc1 VG vgdata lvm2 [256.00 GB / 0 free] PV /dev/sdd1 VG vgdata lvm2 [256.00 GB / 0 free] PV /dev/sde1 VG vgdata lvm2 [256.00 GB / 0 free] PV /dev/sdf1 VG vgdata lvm2 [256.00 GB / 0 free] PV /dev/sdg ...

I've been playing a bit with the nscd now and want to share some tips related to tuning the nscd.conf file. To see how the DNS cache is doing, use nscd -g. nscd configuration: 0 server debug level 26m 57s server runtime 5 current number of threads 32 maximum number of threads 0 number of times clients had to wait yes paranoia mode enabled 3600 restart internal passwd cache: no cache is enabled [other zero output removed] group cache: no cache is enabled [other zero output removed] hosts cache: yes cache is enabled yes cache is persistent yes cache is shared 211 suggested size 216064 total data pool size 1144 used data pool size 3600 seconds time to live for positive entries 20 seconds time to live for negative entries 66254 cache hi...
