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.
View 2 RepliesI am planning to install windows2003 server. Do I need to choose fat32 option or NTFS as file system?
View 9 Replies View RelatedI have been runnin my dedicated server for almost a year. Then suddenly the filesystem becomes corrupt (so the datacenter tell me) (The Planet).
I have used the Rescus Console to boot my server, I have managed to mount the /home partition and can access all sites files/folders.
I am not great with Linux but I really really need to be able to access their databases aswel or best case scenario repair the OS/File System.
IF anyone can help me here or help me via messenger. I cannot afford much but I would be willing to pay for someone to assist me with this.
I wanted to mount a Usb portable drive of some data I have inside my Linux server and make them read on my Windows xp.
The drive has been formatted as ext3 and it just won't show in "my computer" inside Windows unless I reformat it again as ntfs.
The same turns around if if I format as ntfs, and i can't mount it under linux with the message "mount: unknown file system type 'ntfs'"
After running ontrack easy recovery tool we have recovered 172 Gb of data from one of the hard drive but everything is in *.dat format.
how to get the data from here.
My raid 1 failed and it wouldn't be such an issue except that the other drive wasn't syncing for 2 months for some reason.
So now I have to try to recover it to get the info.
It seems that the drive seems to be ok yet I am unable to boot to it.
Using supergrub I was able to boot to a kernel but when it starts loading there is a kernel panic.
Error is basically
EXT3-fs: unable to read superblock
mount:error 22 mounting ext3
When I use Rescue option using a centos CD, I am unable to mount the HD.
Using Knoppix,I was able to see the HD but unable to mount it since it claims the 2nd partition is no clean. Since the HD was raid, I don't think thats the problem at all.
Is there anything you guys can advise me? I'm somewhat new to doing this and really green on Raid for that matter.
Whats a good method to find the superblock?
We have a server with a hdd issue. It is showing up as drive O but we can not access it. It seems like the NTFS is corrupt or something. Windows does recgonise there is a drive and labels it but thats about it..how can we recover this?
View 2 Replies View RelatedI 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 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.
more experience Linux users to partition my dedi into VPS. 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?
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?
Does the use of partitions prevent hackers from getting access to the entire Unix server?
