[CentOS-es] Clonacion de disco
Hola a todos, Tengo un servidor CentOS 5.2 con un disco de 40 GB y lo he clonado con el programa G4L a uno de 250GB, todo va bien, excepto que me marca que el disco de 250GB es de 40GB y si voy a administracion de volumenes logicos me sale el resto del espacio de disco pero como uncategorized y me pone particinonar manualmente.

[CentOS] resize LVM (ext3)
Hello guys, my scenario is following 1. I have LVM group named system 2. I have a logical volumes - system/root , ext3 mounted as / (20GB) - system/swap, swap - system/home, ext3 mounted as /home (431GB) I need to shrink system/home to 80GB (currently there is 57GB used) and use free space to create another logical volumes. My scenario is 1. reduce ext3 fs size to 80GB by using resize2s 2. reduce system/home size by using lvreduce 3. create another logical volumes Questions 1. How can i be sure that i will shrink ext3 to exact size 80GB and that the same will lvreduce do? I do not want to cut from ext3 filesystem if i will reduce logical volume too much 2. Can you please send me commands to achieve 1) and 2) part of my scenario? 3. Or can i just use lvreduce and my ext3 will shrink automatically? 4. Do i need to umount system/home when resizing?

See: http://www.redhat.com/docs/en-US/Red_Hat_Enterprise_Linux/5.2/html/Deployment_Guide/s1-swap-what-is.html Swap should equal 2x physical RAM for up to 2 GB of physical RAM, and then an additional 1x physical RAM for any amount above 2 GB, but never less than 32 MB. So, if: M = Amount of RAM in GB, and S = Amount of swap in GB, then If M 2 S = M *2 Else S = M + 2 Using this formula, a system with 2 GB of physical RAM would have 4 GB of swap, while one with 3 GB of physical RAM would have 5 GB of swap. Creating a large swap space partition can be especially helpful if you plan to upgrade your RAM at a later time. For systems with really large amounts of RAM (more than 32 GB) you can likely get away with a smaller swap partition (around 1x, or less, of physical RAM).

That's a silly recommendation, and never been true for Linux. RedHat don't always know what they're talking about. In older BSD systems (eg around SunOS 4 times or before) swap space was utilised oddly; all memory was allocated from swap, so you needed _at least_ physmem of swap just to use all your real memory! So if you added physmem of swap then your total virtual memory size was still only physmem. No help! So the rule of thumb came along that said swap = 2*physmem and that gave you a VM of 2*physmem. Linux never did this (and I don't think modern BSDs do, either) so adding physmem of swap will automatically give you twice physmem of VM. So the old BSD 'swap=2*physmem' rule of thumb is now a linux 'swap=physmem' guideline instead. But it's still just a rule of thumb, or a guideline. How much swap you need depends on your circumstances and load. If you have 4Gb of RAM and find the system is using most of it for cache then you may not even need any swap! -- rgds Stephen ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

[CentOS] Can one invoke multiple INSTANCEs of Firefox on CentOS

Is this even possible? I have a sense from the small bit of testing that I have done that even with separate profiles and invoking the firefox process manually from different terminal windows does not provide a completely separate running instance on the desktop.

I've been using SATA disks with centos since the early 4.x days without issue, so you have me at a bit of a loss here. I'd say if anything it's due to controller support, and much of that can be chalked up to what hardware vendors are pawning off as 'controllers' these days. I recently set up a CentOS 5.2 server with RAID 1 (software) and 2 sata drives. During burn-in I see no problems. I'm using a Supermicro PDSBM series system board.

Re: [CentOS] Re: Apparently no swap configured

So if you added physmem of swap then your total virtual memory size was still only physmem. No help! So the rule of thumb came along that said swap = 2*physmem and that gave you a VM of 2*physmem. old codger hat this was also how early IBM System/370 DOS/VS worked... the swap space (which was contiguous cylinders of the disk, btw) was mapped 1:1 to virtual memory address space /old codger hat now, on late model Solaris, 'swap' is also used as tmpfs, which /tmp and /var/run utilizes by default, so you definitely want to allocate sufficient swap space for this at least, regardless of how large your physical memory is. ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
