RE: [CentOS] Upgrade ram and what to do with SWAP PARTITION ?
I have a swap file of 512mb because i was using 256mb, now i already have 512mb ram installed and the swap continue on 512mb, the system is acting better now. System monitor says: CPU History 3.0 or 4.0 % User Memory: 224mb of 495mb Used swap: 0 bytes of 512mb I have running one windows of firefox while viewing in system monitor. Don't know if this values are okay I think they are normal but I don't have to much experience. Do you think I need to make some change in swap partition like going to 1gb, if so, where can I find some help in doing that? Thanks for your help.

How much swap do you currently have? You may not need to increase swap at all. If you do - I haven't tried this method in CentOS (or any OS) but it should work: https://help.ubuntu.com/community/SwapFaq#head-75ffcb00cefe143fc380f84d7ea92 03f16a596d0 It creates a swap file instead of a swap partition. Much easier than finding unpartitioned space ... ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

Yes and with today's kernels it provides the same level of performance. # dd if=/dev/zero of=/.swapfile bs=1M count=512 # mkswap /.swapfile fstab: /.swapfileswapswapdefaults0 0 Or if you use lvm, turn swapoff the lv, lvresize the lv, mkswap the lv again, then swapon the lv and you have a larger swap, but the swapfile will at least be contiguous. -Ross __ This e-mail, and any attachments thereto, is intended only for use by the addressee(s) named herein and may contain legally privileged and/or confidential information.

RE: [CentOS] Upgrade ram and what to do with SWAP PARTITION ?
Thanks again, i did the change, i follow this steps : http://www.linuxtopia.org/online_books/centos5/centos5_administration_guide/ centos5_s1-swap-adding.html#s2-swap-creating-file But I setup bs=1M count=1024 this I learn it from: https://help.ubuntu.com/community/SwapFaq#head-75ffcb00cefe143fc380f84d7ea92 03f16a596d0 I like it more to do it that way. Later I reboot my PC and run the command free, it seems that now I am using my newly created swap file, what a nice start. My linux experience is starting to like it more, thanks to all for your help, thoughts and time!
