01 Apr '05

How do I get this set up? spamassassin -D --lint shows me an error... debug: bayes: no dbs present, cannot tie DB R/O: /root/.spamassassin/bayes_toks and with no db present, it doesn't learn. Is there something simple that I'm missing? Craig

[CentOS] Lost all info in a file server because of LVM - HEEEELP ME, please
by Mário Gamito 01 Apr '05

01 Apr '05

Hi, I'm totally desperated. I have this file server with a total of about 200 GB of my user's files. The server has "3 in 1" discs, using LVM. Somehow, i don't know why, the LVM info is gone and i cannot access my file system. I had in LVM: sda1 -> /boot sda2 -> / sda3 -> /home (where all the Samba shares resides). sda4 -> swap sdb sdc Tha machine now starts with a single partition ( / ) mounted on /dev/root From there i can manually mount under /mnt partitions "/boot", "/", but NOT "/home". Trying to mount /home, i always get the busy error. I cannot unmount the "/" on /dev/root, obviously. How can i (if possible) restore the LVM info ? I have a backup from Sunday, so, it's really not a life or death case, but nevertheless it is a real annoiance, and the server is already down for 24 hours :( Any help would be apreciated. Warm Regards, Mário Gamito

Odd Question... MAX Ram Disk Size
by Scott Heisler 31 Mar '05

31 Mar '05

Greetings, Before I get slammed, I've looked all over the internet for the answer to this (googled and more) and haven't been able to find what I'm looking for. Here's what I need. I have a server that I use to hold workstation images. I use a Linux boot CD combined with some scripts I wrote and some disk imaging software to allow me to image windows workstations. Anyway, when I roll out a new workstation Image, I may roll it out to 20 or 30 computers at once, all using the same image file (base build). I want to put that image file on a RAMDISK on my server. The image file is between 3 and 4 gig. I have 6 gig in the server, so plenty of memory. I modified GRUB to increase the size of my ram disk... First I started with a 200mb, that worked group, formatted, etc. Then I tried 1gig - everything looks like it works but when I mount it, it tells me the volume is not formatted or has invalid super blocks. Perhaps I'm exceeding the allowable built-in ramdisk limit, but I couldn't find any docs anywhere that would tell me what that limit was. Does anyone know of an alternative ramdisk product, that does not load at boot time, where I could do what I need (as described above)? Or does anyone know how I can get a 4-gig Ramdisk to work properly? I'm running the new CentOS 4 on the server. Thanks for any help. I did spend 2 days doing Internet research with no results, prior to posting here. Thanks. Scott

RE: [CentOS] Odd Question... MAX Ram Disk Size
by Scott Heisler 31 Mar '05

31 Mar '05

Thanks everyone for the great INFO... This was EXACTLY what I needed and had a very hard time finding out. The mount -t tmpfs -o size=1g none /ramdisk worked perfectly. I needed temporary ram space to use as disk space. Thanks! Just to explain further, the "images" are not ISO's... These are hard drive images, like GHOST files (only using a Linux free application). But to further explain, even if I mounted an ISO, there would still be disk IO.. I'm trying to eliminate the disk I/O from the equation so I can be downloading 20 or 25 machines at the same time. Since the server us a dual 2.0gig Xeon and I have gig all the way from the server to the desktop.. This should scream! Thanks again.

OK. time to make some contribution (centos4/ppc)
by Pasi Pirhonen 31 Mar '05

31 Mar '05

Hi, Even now someone is actually installing (i see that from the ftp-server logs) the centos-4/ppc beta-version from announced place. You people have to stand up and _TELL_ me what kind of hardware _IS_ working, so we would know more than already know - 43p works. I can't believe that all those, who installs, does have 43p too? Please? Something, so if it's actually working on something else than already known 43p, we'd really like to hear about it. If it's not working, we'd still ike to hear about it as one can't fix anything not known to be broken. Someone something, so eventually there would be release? -- Pasi Pirhonen - upi(a)iki.fi - http://iki.fi/upi/
