Talk about existing forums
by Karanbir Singh 07 May '10

07 May '10

hi guys, One of the things that came up from the last chat about the language specific websites, was that there was no one on that call who actually used the forums. With the help of Akemi, I've been able to setup a meeting for the existing english forum moderators to come together and have a chat about: 1) what we have right now 2) Whats broken 3) whats really good 4) where they would like the forums to be in the next 6 months 5) Where they would like the forums to be in the next 12 months 6) The idea of 'English' as being just another language Its a bit short notice, but the meeting is setup to happen on Wednesday 9th Dec at 2300 UTC. Its the only time that worked for all concerned - in the next few weeks period. Apart from the existing forum moderators, anyone interested in the conversation is more than welcome to come along. Lets all sync up at 22:50 on #centos-devel(a)irc.freenode.net and take it from there. Also, lets try and timebox initial discussion to 40 min with a further 10 min after that to summarise and plan future actions. - KB

Hi Guys, This just came through. Is there any interest in the Alpha platform amongst people here ? Also, these guys are based in the US - so a US based home would be ideal for these machines.

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
