removing inaffective SAN partitions from the system .....
by Jagan Kommineni 19 Apr '10

19 Apr '10

Dear All, I have installed CentOS release 5.2 (Final). EMC SAN partition is mounted by using EMC Powerpath for resolving multiple paths. I was able write and read data over to SAN partition without any issues. Subsequently I have unmounted EMC SAN partition from the system and deleted LUN using Navisphere user interface. After rebooting system, I still see SAN mappings in system. Here is the affected partition mappings .... ============================== cat /proc/partitions ============================== major minor #blocks name 8 16 1048576 sdb 8 48 1048576 sdd 8 80 1048576 sdf 8 112 1048576 sdh ============================ When I try to print information using parted, I am getting the following information .... ========================================================================================= #parted /dev/sdb GNU Parted 1.8.1 Using /dev/sdb Welcome to GNU Parted! Type 'help' to view a list of commands. (parted) print Error: Unable to open /dev/sdb - unrecognised disk label. (parted) ============================================= I would like to get rid of partition mappings from the system. Anyone has any solution for this problem please. with regards, Dr. Jagan Kommineni Ludwig Institute for Cancer Research Parkville Dr. Jagan Kommineni Ludwig Institute for Cancer Research Parkville This communication is intended only for the named recipient and may contain information that is confidential, legally privileged or subject to copyright; the Ludwig Institute for Cancer Research Ltd does not waive any rights if you have received this communication in error.

I have edited the subject line to make clear what we are going to discuss. :D I remember the major work of the last update was done by Ralph with extensive help from Fabian and other community members. I hope they can continue the effort. :) Akemi

squid init script
by Roman Garifullin 19 Mar '10

19 Mar '10

Hello all! I'm sorry if I wrote wrong place, but may be your will look at my patch to /etc/init.d/squid script in CentOS 5.4. The reason to rewrite it was the need of launching two process of the squid daemon with different config while original script was unable to do this easy. Now, one who need this, will change squid's config file and /etc/sysconfig/some_new_name_of_squid and just can make a hardlink in /etc/init.d. Very simple. Sory for my bad english
