We have a CentOS 3 server with about 300GB of data on an ext2 filesystem that we need to mirror onto a new drive, which we're then going to pull out and put into a second server. A straight disk-to-disk copy (with rsync, tar, or "cp -a" doesn't much matter) manages about 75MB per minute, which would take almost three days, and the system gets very sluggish while such a copy is going on, so we can't afford to just let it run. Is it possible, without loss of data, to convert the existing ext2 filesystem into a mirrored software RAID, then add the new drive as a secon...

Hi, I had a Debian woody server with samba as PDC with LDAP backend in the same box, and mixed windows clients (98, XP, etc). The clients accessed a 75MB MS Access database (.mdb) that was put in a Samba share. Everything was fast... everything was good... But, last week I decided to upgrade to debian Sarge, so as you know Samba was upgraded to Samba3 too (3.0.14a), and now if a user tries to open the database and is the first user accessing it,...

Hello, I'm a bit desperate so I'm trying to seek help here. Many year ago, I built myself 2 file servers (5 disks enclosure for data, 2 disks enclosure for the OS) on a computer. It was running on Debian 7.11 for years without an issue and I was getting 75MB/95MB when transferring file from it to a Windows client, all having a 1gbs network card. https://i.ibb.co/N618Z4W/Debian-7.png However, after upgrading to Debian 8 and more recently Debian 11, I keep noticing a? huge performance drop. The near 100 MB drop to a roller coaster of between 25MB and...

Note that I did the install with 256Mb memory, and I may upgrade to 512Mb. / (root) partition of 6Gb recommended. /boot partition of 75Mb (that seems to be met) /swap partition of x2 installed memory /var partition of at least 10Gb (well that is based on a 100 users and 100mb and that is enough for me) There is also the note: Some versions of Linux include the Logical Volume Manager (LVM).

...which have been modified with R- -> NA) because when I tried to do this conversion operation previously it got about ½ way through then crashed. The problem is that it crashes *this time* too, without displaying a prompt to say it’s read a single file. The file it gets stuck on is about 75mb in size. I am using a dual-core 3.2Ghz Pentium D processor with 2 Gb memory (& 2Gb virtual memory), and (unfortunately) Windows XP. Questions: 1) Any general tips on how to increase the amount of memory available to process the file? 2) Can you see a more efficient way of doing what...

Hello I have create a bootdisk with isolinux. These cd load an initial ramdisk (75MB) as rootfs, start the init process and some service (e.g. network, inetd) and gives me a valid loginshell for working (recover the system from a backup). Now i found, that some of my machines cannot boot from cdrom (the controller doesn't support this). Q: Is it possible to create a floppy b...

Hi all, I am doing some intensive computation right now. My system is Pentium4 3.20G + 1.0G RAM + WindowsXP + R1.9.1. It seems my computer is very powerful. However, when I do some simple matrix algebra operations based on a matrix (DD) with dimension 5000000 by 2, I found that the consumption of RAM is huge. For example, the command a <- 1 - DD[,2] eats my 100M RAM. Does anyone know how

Presumably I could just change the above message to say Please install choropltherZip by typing: library(devtools) install_github('arilamstein/choroplethr at v1.0.0') But I don't know if this is the best way to do t...
