I have an dedi with 2 x 250 gb hd's with raid-1.
Now I just have one partition / for whole drive.
Should I re-install and make proper partitions?
Which partitions you recommend??
I will backup to a local folder /cpbackup and rsync from there to nas.
Is it possible to specify where your CPanel user's data is stored?
Let's say I have four hard drives without RAID, I have hard drive one on /home, hard drive two on /home2, hard drive three on /home3, and so on. Is it possible to setup users on the different partitions to spread out disk usage?
To explain further, I would like to set it so maybe one reseller account was using /home2, then another was using /home4, and another using /home.
Any ideas on how to go about splitting up user's data across seperate partitions?
I have a linux server with cPanel and 500GB Disk Space. After investigating I think I would have the following partitions.
/
/boot
/home
/dev/shm
/tmp
/usr
/var
how much to allow to each partition. I will be using the server for hosting accounts, shared and resellers.
Also what would you recommend the swap file size be?
I have a Vista machine. I have installed CentOS 5.1 by selecting the C: (Active partition) and formatting it as ext3 partition. Then after installation, in the Hardware > Hard disks, it is showing only one NTFS partition. But actually I have 4 NTFS partitions. When I try to mount that partition using ntfs-3g, I am getting "/dev/sda3: permission denied" error.

I have an Intel Quadcore 2.4 Ghz, 500GB HDD, 2GB DDR RAM, dedicated server with a max 100mbit connection and 2000GB BW/mo. It has Centos 5.3 (centos-release-5-3.el5.centos.1) installed on the server and I want to install the DirectAdmin CP soon.
I'm not a reseller or webhost and don't intend to become one. This server is for my exclusive use.
I want to use half the server to run virtual instances of a Windows 2008 server and a KDE or similar Linux virtual desktop using FreeNX as well as a 4PSA VoIP Now or similar software. The other half of the drive will be to run my businesses websites, mailserver, a DNS server, etc.
I have six IP addresses for this server that can be used to this end and will host at least three websites (under separate domain names) and one or two blogs for which I will install requisite software.
I understand that the RHEL 5 embedded virtualization software will allow me to partition the server into VPS for various purposes.
Here are the outputs from ckdisk -l and parted -l respectively for the current HDD partitions.

For the DA install, so I don't have to try to figure out where things are, I'd like to use their more complex partition structure as follows:
/boot 40 meg
swap 2 x memory
/tmp 1 Gig. Highly recommended to mount /tmp with noexec,nosuid in /etc/fstab
/ 6-10 Gig
/usr 5-12 gig. Just DA data, source code, frontpage.
/home rest of drive. Roughly 80% for user data. Mount with nosuid in /etc/fstab if possible.
I will install dovecot to be able to create SSL access to my webmail so don't need a '/var' directory.
What I want to know is:
1) Should install virtualization and partition the drive prior to having DA installed?
2) How do I best partition the drive into VPSes so I can run distinctly different virtual instances of different OS and/or programs on the VPS as well as use half for websites, blogs, servers, etc.?
3) What else do I have to keep in mind when doing this?
I'd appreciate any positive, useful response and information on getting this done and I'd like to try to get this done by Monday or Tuesday of next week so DA can be installed on the appropriate partition.
We're outgrowing our current bulk storage system and I'd like to solicit opinions.
With 2 TB disks and a 16 disk array, it's possible to have a single 28 TB volume (after deducting RAID5 parity overhead and a hot-spare disk). I've seen arrays from Aberdeen with 48 and 96 disks, for nearly 200 TB. Windows supports up to 256 TB per volume when 64K cluster sizes are used.
Our backup system uses a ton of storage space, and it would be far more convenient, and more efficient from a utilization standpoint, to access that space as a single volume.
Breaking it up into smaller chunks, such as 2 TB each, means we have to make a "best guess" on balancing actual need.
For example, if we assign 25 servers to each 2 TB volume for backup storage purposes, some volumes might only see 800 GB of consumption (remaining 1.2 TB allocated but not used) while other volumes might get 1.6 TB used (remaining 400 GB allocated but not used). Key concept: wasted space, because we have to over-estimate need to assure adequate headroom.
From the opposite viewpoint, if we had a sudden increase in need that exceeded the available space allocated to that volume, we'd have to move that server to a different volume. Key concept: increased admin workload to monitor and re-balance distribution as needed.
Now if we used one giant volume, there would be no guesswork, no "allocating more than we think is needed" for a bunch of small volumes. All servers share one huge common pot.
But there has to be a practical limit from a system-overhead standpoint. Our backup sets consist of a few multi-gigabyte files, so using 64K clusters will not cause much waste from slack space.
I'd like to get your opinions on maximum disk volume sizes from a practical standpoint.
I just installed a new server with partitions below
# df
Filesystem 1K-blocks Used Available Use% Mounted on
/dev/mapper/VolGroup00-LogVol00 470889384 2015312 444568408 1% /
/dev/sda1 101086 28075 67792 30% /boot
/usr/tmpMnt 290503 10289 265214 4% /tmp
However, in HyperVM, it shows
VolGroup00 465.53 GB 465.53 GB
/(VolGroup00-LogVol00) 25.7 GB 459.85 GB
And I could not create vps on each. Error message is not_enough_space[].
I have searched on lxlabs board, and seems I need another partition for data?
Does the use of partitions prevent hackers from getting access to the entire Unix server?

I'm wondering if anyone here has successfully used PHP 4 and 5 on CentOS 5 with cPanel.

how to install mod_top on a Cpanel / Centos box?
[url]
This does not work (gives off errors such as file or dir not found)
(The box, 2 years now, never had issues before all you will read...)
I do have a box at the IP xxx.xxx.xxx.xxx, which on 15th Nov. was: AMD 4200+
with 300 GB hdd for OS, and CentOS 4.5 on it...
Because the system was facing few load problems of wrong installed applications, we decided to do a fresh OS reload to the latest OS version and
cPanel.
on 16th Nov, the box was up and running with CentOS 5, and cPanel 11.
the kernel is: 2.6.18-8.1.15.el5
After few hrs the box was done and IO restored all backups in it anbd all worked fine, I realized that I couldnt access cPanel, page was blank for
everything.
Also, most pages (except simple html) where showing internal error 500.
I did a reboot. probelm was fixed.
After few hrs, problem came up again...
I left ssh logged in to see whats wrong.
I found out that every few hrs, that issue was happening:
Message from syslogd@server at Sun Nov 16 11:47:21 2007 ...
server kernel: journal commit I/O error
Then, we had techs to check HDD for errors. they did fsck, and said disk has to be replaced (at this point, without wanting to offend anyone, I have to state that 90% of techs in datacenters, or at least at mine --won't name them, 99% you guess which DC it is...-- are just low paid students that don't know SIMPLE things...) so we told them to replace the HDD and do OS reload in new drive...
So, on 17th Nov. we had online a new HDD, 400 GB with CentOS 5 loaded in it, and cPanel 11...
After few hrs and all working and backups recovered, the issue came up again!
This time, with exactly same error, techs told us it may be RAM, so they replaced the RAM and we waited...
In 2,5 hrs, bang, it happens again, same error.
They say, it might be the sata cable...
we replace it...
AGAIN ERROR.
we ask them to loook at it seriously, and after lot pressure, to avoid case that mo/bo or controller is wrong, they do upgrade us in a BRAND NEW colocated box, which was this time: Intel Core 2 DUO, 6300, with brand new 500 GB HDD and new RAM.
We recover in the new box the backups.
Box is online today at 18th Nov...
and the issue comes up again!
Message from syslogd@server at Sun Nov 18 11:47:21 2007 ...
server kernel: journal commit I/O error
I ask them what the **** is going on now and why after having all hardware replaced with new, and all OS reinstalled clean on new drives and new devices, 3 times, why we have again the same error...
And their response: power cable was loose, we replaced power cable...
Guys, sorry, this is really DUMP... loose cable cannot give that error...
and the error... continues!
Also, at this point, I have to let you know, that when this error comes up, (Message from syslogd@server at Sun Nov 18 11:47:21 2007 ...
server kernel: journal commit I/O error) the filesystem becomes READ-ONLY and
nothing gets affected, if we do a cold reboot by reset button, it comes up
again and all work PERFECT, until the issue comes back again.....
I am desperate with that, let me know what I have to do!
