crontab won't work
by Niki Kovacs 31 Oct '09

31 Oct '09

Hi, I have a strange problem here. I have two servers, one dedicated webserver, and a local backup server. On the webserver I have this : [root@12569hpv163154:~] # crontab -l 00 22 * * * /usr/local/bin/sauvegarde-pmbccps.sh This launches a backup script every day at 22:00, and it works as expected. Now here's what I have on the local backup server : [root@grossebertha:~] # crontab -l 24 17 * * * /usr/local/bin/sauvegarde.sh Here, the script /usr/local/bin/sauvegarde.sh basically launches an incremental backup with rsync over SSH. The script is executable OK, it works very well when launched by hand on the command line... except cron won't start it. Here for example I tried to launch it on 17:24. Nothing. I checked the machine 'date', it's OK. Now I don't have the slightest clue why this doesn't work. What's the magic word here ? Cheers, Niki

RAID 10 on Install?
by ML 31 Oct '09

31 Oct '09

Hi All, How can I RAID 10 on install? (the names myRAID1 and myRAID2 are just for example purposes) I select a custom layout.... /dev/sda, sdb, sdc, sdd are listed... I create a partition of Software RAID on each of sda, sdb, sdc, sdd Create a swap partition on sda? Click RAID and take sda and sdc and RAID 1 to myRAID1 Click RAID and take sdb and sdd and RAID 1 to myRAID2 Click RAID and take myRAID1 and myRAID2 and RAID0 to MYRAID This leads me down to swap. If I create swap on sda, then dont sdb, sdc, sdd then all have unused space of the size of swap on sda? What is the rule of thumb for Swap these days. Back a long time ago it was double the RAM in the machine.....but that was a long time ago, what is best now? Thanks for the chat! -Jason

Stripe vs Cylinder alignement...
by John Doe 30 Oct '09

30 Oct '09

Hi, I modified my kickstart to do some custom partioning and formating in a pre-install script. I am trying to align the partitions on the RAID stripe (and format with a correct stride). But, sfdisk complains that it does not start/end on a cylinder boundary (used -L option to limit complaining). Since the cylinder size is not a multiple of the stripe size, I cannot align on both. I tried to align the begining on the stripe and the end on the end of a cylinder, but sfdisk still compains... Basicaly, I have a 128KB (256 sectors) stripe, and 255*32 = 8160 sectors cylinders. What I am doing is: begin = ( begin / 256 ) * 256 end = ( end / 8160 ) * 8160 -1 So, for my first partition (96MB): begin=256 size = ( ( 96 * 1024 * 2 ) / 8160 ) * 8160 = 195840 sectors end = 195840 - 1 - 256 = 195583 Any idea what I am doing wrong in my calculations or logic? Thx, JD

Hi! Did anyone tried this on 5.4? having a look on http://wiki.centos.org/HowTos/Install_On_Partitionable_RAID1 is would seem that that mkinitrd patch is no longer required. Can someone ack this? Thanks, Adrian

Default ACL question (EXECUTE BIT)
by Jorge Fábregas 30 Oct '09

30 Oct '09

Hello everyone, I'm doing some tests with ACL's and even though I can create a "default" ACL for a directory (that includes "rwx" for the default owner), when I finally create a file wihin that directory the execute bit is chopped off: [joe@machine ~]$ mkdir mydir [joe@machine ~]$ setfacl -d -m u::rwx,g::-,o::- mydir/ [joe@machine ~]$ cd mydir [joe@machine mydir]$ touch testFile.txt [joe@machine mydir]$ ls -l testFile.txt -rw------- 1 joe joe 0 Oct 29 21:14 testFile.txt I don't think umask is involved here. As far as I know umask isn't involved when dealing with default ACL's. Anyhow, I'm pretty sure this is by design (security-wise). Is there any way to override this behaviour? Thanks, Jorge

RAM errors after kernel-update
by Michael Schumacher 30 Oct '09

30 Oct '09

Hi, I updated a server yesterday from "kernel 2.6.18-128.7.1.el5xen" to "kernel 2.6.18-164.el5xen" After rebooting, my message log is flooded every second or so with this error messages: Oct 6 14:52:20 xenserver1 kernel: EDAC MC0: UE row 0, channel-a= 0 channel-b= 1 labels "-": NON-FATAL recoverable (Branch=0 DRAM-Bank=0 Buffer ID = 0 RDWR=Read RAS=0 CAS=0 NON-FATAL recovera ble Err=0x2000 (FB-DIMM Configuration Write error on first attempt)) and Oct 6 15:17:23 xenserver1 kernel: EDAC MC0: CE row 0, channel 0, label "": Corrected error (Branch=0 DRAM-Bank=0 RDWR=Read RAS=0 CAS=0, CE Err=0x10000 (Correctable Non-Mirrored Demand Data E CC)) The machine is a new Tyan S5397 mobo with 16GB Kingston RAM KVR667D2D4F5K2/8G Removing and replacing memory to different locations doesn't make any difference. After some digging, I noticed that the new kernel has added support for the i5400 chipset. I found some reference that the new kernel has this error reporting capability the old one hadn't. Question1: how many recoverable RAM errors are acceptable? Question2: The error appears always with the same id in the error message. Mobo problem? Question3: Are there any recommended BIOS settings to operate the RAM slower to see if the problem disappears? Question4: Any other proposals. Being located in Germany makes the "just return it to the dealer" proposal quite unattractive. best regards --- Michael Schumacher PAMAS Partikelmess- und Analysesysteme GmbH Dieselstr.10, D-71277 Rutesheim Tel +49-7152-99630 Fax +49-7152-996333 Geschäftsführer: Gerhard Schreck Handelsregister B Stuttgart HRB 252024
