Hello, I am confused by a warning from mkswap : When making a swap on a LVM volume, I see the following warning : mkswap: /dev/vg_SDB1/swap_test6_64: warning: don't erase bootbits sectors on whole disk. Use -f to force. Setting up swapspace version 1, size = 1048572 KiB Is it safe to use mkswap -f in this case ? (If that matters, the swap is intended for a virtual machine, and the host where I am using mkswap is a CentOS-6 server.) Thanks, -- Philippe Naudin

Hi, I have loaded CentOS 5.6 on HP DL 180G6 2U Rack Server and the physical RAM is 32 GB. As per http://www.centos.org/docs/5/html/Deployment_Guide-en-US/ch-swapspace.html It says it should be 1 x of Physical RAM or less. Not sure about the "less" word in deciding swap space size Please suggest/guide further on what all parameters i should decide to set swap space. Regards, Kaushal

...question - at the bottom - will make sense [when posting to lkml i often get questions asked that are answered by the background material i also provide... *sigh*] each virtual machine requires (typically) its own physical ram (a chunk of the host''s real memory) and some virtual memory - swapspace. xen uses 32mb for its shm guest OS inter-communication. so, in the case i''m setting up, that''s 5 virtual machines (only one of which can get away with having only 32mb of ram, the rest require 64mb) so that''s five lots of 256mbyte swap files. the memory usage is the m...

Though the R computations thrash my system (FreeBSD, K6-233, 64MB). I have to triple the swapspace before starting, and I wait about an hour for either rebooting the system or having a lucky outcome. There seems to be something fundamentally wrong. It seems I have to move to nmle to get variance components. I did not manage to translate my problem to mle language yet. Thanks for any help --...

I've read through the RSync man-pages and FAQ on the net. There it has been suggested to play around with some options like blocking and non-blocking-io and bwlimit. This didn't change anything. I furthermore did leave RSync alone a whole weekend, but no further files have been processe...

I am running rsync on win9x (PIII 900, 128MB RAM) between a mapped network drive and a local drive. For small folders on this machine rsync works great, but the folder I am syncronising with has 13GB of data and > 1,000,000 files. Out of about 20 attempts rsync has only succeded once, all other times it just seems to hang. Not much info but any ideas? Thanks Scott

Hi ALL, I have a harddisk with 3 primary partitions and one extended partitions. Under extented partions , there are 15 partions. Whole hard disk has been partitioned in a standard way, (i.e NOT LVM) It has 2GB ram. swap is also 2GB. Now I want to extend this swap to 4 GB. If I use dd coomand and create a file with 2GB, Will I be able to extend the swap witn swapon commnad? How can I achive

Hello everyone, First of all, great job on the 4.8-R. We have been a long standing user of FreeBSD and are very happy with everything. Now my question. I am trying to stress test a new Dell PowerEdge server and find the limits of its hardware and my tuning. Here are the server stats: * 2x Xeon 2.8 with SMP compiled, hyperthreading NOT compiled in kernel * 4 GB of RAM, 8 GB of swap on Raid 1

Hi, I have been using rsync for many years and never had any kind of problem. Lately I am running out of RAM trying to do an incremental backup to a box that only has 2G of RAM. The entire directory structure I'm mirroring is about 200G of files. A minority of subdirectories have many files. Is there a way to do an incremental backup with --delete option that does not use as much memory? Is

Everyone, We just had a pretty bad crash on one of production boxes and the ext2 filesystem on the data partition of our box had some major filesystem corruption. Needless to say, I am now looking into converting the filesystem to ext3 and I have some questions regarding ext3 and Linux software RAID. I have read that previously there were some issues running ext3 on a software raid device

Hi all, i have a question. I''m going to setup a Xen server for a client. It''s going to serve about 25 clients. It''s a Athlon 64 3200+, which currently runs Debian i386-stable and xen 2.0.7 until Xen 3.0 is stable enough, and then i''m gonna replace it with Debian amd64-stable and Xen 3.0. The Xen dom''s consists of: Samba , file printer sharing most

Hi All, This is out of the topic question, but I''m hoping that you can help me. If for example I''m going to install a Fedora 4 64-bit with 8 to 12 Gig of physical memory, how much swap file of directory do I need to create? Thank you very much, Wennie
