Which file system to use for a USB backup
by Todd Cary 13 Mar '11

13 Mar '11

I have some photographs on my Centos 4 server that I want to copy to a USB drive. However, I want to be able to access the files from Windows or Mac OS's. Where should I look for instructions on how to mount and format the USB drive and is FAT32 the only option? Many thanks -- Ariste Software Petaluma, CA 94952 http://www.aristesoftware.com

12 Mar '11

Hi, Anyone here using Nginx as alternative to apache in conjunction to php scripts? Care to share thoughts and caveats? I am reading that it is a good alternative but do not know the real life limitations, diferences to apache, which repo to fetch etc.

What iSCSI is used in Centos 5 and RHEL6?
by Emmanuel Noobadmin 12 Mar '11

12 Mar '11

I was looking up on iSCSI in preparation and became aware that there are different iSCSI software/drivers/whatever-is-the-correct-term available. e.g. IET http://iscsitarget.sourceforge.net/ SCST http://scst.sourceforge.net/ STGT http://stgt.berlios.de/ LIO http://linux-iscsi.org/ Based on what I can see, it seems to be STGT because the site provides a link to Redhat advisory which seems to imply that it's what's being used in RHEL. Does anybody know for sure?

There were delays after changes after delays for that project that was meant to run on the VM setup. Spent more time hacking temporary solutions to their problems with NAS and such. So I haven't actually got this done. But if you can wait, I could probably answer you in about 4 weeks... when the hardware and fibre connectivity for the client's server room comes in.

I don't have any choice as to when the drives are spun up (only on bootup), but I did try a controller card which pre-spun and checked the identification of the drives before handing off to the BIOS for bootup. That didn't help. On the particular Supermicro motherboard I'm using, there is a very long delay (10 or 15 sec) between power-on and initiation of visible BIOS activity, so all disk drives have ample time to spin up and stabilize. The drives' SMART data shows that the average spin-up time is well within the BIOS startup delay. Each drive activity indicator shows that they are always probed by the kernel's scsi scan process. I have since tried a couple of other tricks I found by Googling around ... setting the kernel parameters 'rootdelay=xx' and 'scsi_mod.scan=sync'. These had no effect on the problem. For some unfathomable reason, the last drives in each group of drives have one or more random partitions missing, with no 'bind' statement in dmesg. Other partitions on those drives are bound normally. This has been tested with at least two known-good replacement drives, with the same random results. On two occasions today, everything worked perfectly, but that was unusual. A friend of mine suggested an ugly hack - connect two 'dummy' unused old SATA drives to the last port of each controller (I'm using only 6 of 8 on each). I wonder if one of those $15 IDE-to-SATA converters would do the job (without a drive attached)? Foolish thought :-/ Chuck

screen saver unlock dialog window is not visible in clone mode
by DarkKnight BrightWarrior 12 Mar '11

12 Mar '11

Hi, Environment: I am using CentOS 5.3 operating system. I upgraded xorg of centos to 7.3. I am using intel 945 GM board. My xorg server version is 1.4.2 and inetl driver version 2.4.3. gnome-screensaver version is 2.16.1-8.el5. Problem: I connected another system of same hardware using VGA output. Now I can see clone of my system on secondary display. I enabled screensaver with 1 minute period and also enabled locking feature using gnome-screensaver-preferences. After 1 minute screensaver appeared on both primary and secondary displays. But when I move mouse or press any key, Screen saver unlock dialog is not appearing. But when I type password, I am able to comeout of screensaver. So Screensver unlock dialog is there but it is not visible. When I remove secondary display, I mean when I am in single display mode screen saver unlock dialog is visible and working fine. So what could be the problem that causing screensaver unlock dialog window to appear/visible in clone/extended monitor mode. Please help. Thanks
