Raid Disk Partition Errorc :: Warning: Invalid Flag 0x0000 Of Partition Table

Mar 16, 2008

I have a disk in raid, but it seems raid is not working correctly. I took it out, and plug into another server without raid. However, fdisk shows error


#fdisk /dev/sdb
device contains neither a valid DOS partition table, nor Sun, SGI or OSF disklabel
Building a new DOS disklabel. Changes will remain in memory only,
until you decide to write them. After that, of course, the previous
content won't be recoverable.

The number of cylinders for this disk is set to 20023.
There is nothing wrong with that, but this is larger than 1024,
and could in certain setups cause problems with:
1) software that runs at boot time (e.g., old versions of LILO)

2) booting and partitioning software from other OSs
Warning: invalid flag 0x0000 of partition table 4 will be corrected by w(rite)

Command (m for help):

Should I correct the partition table now, or should I put it in another raid for checking?

Partition Scheme For CPanel

May 31, 2008

I just received a new server, I have been using always the partition scheme 'x2 ram swap, 1GB /tmp, /boot and /", but im not sure if I should get the new server re-formatted with that scheme (the HD is 250GB, so I will get 2GB /tmp), or stay with the current one:

Filesystem Size Used Avail Use% Mounted on
/dev/sda5 7.8G 343M 7.1G 5% /
/dev/sda8 198G 1.1G 187G 1% /home
/dev/sda6 996M 39M 906M 5% /tmp
/dev/sda3 7.8G 2.4G 5.0G 32% /usr
/dev/sda2 9.7G 390M 8.9G 5% /var
/dev/sda1 122M 11M 105M 10% /boot
tmpfs 1014M 0 1014M 0% /dev/shm

I dont really see anything better, since I have all the available space in my old scheme. Anyway, which one do you think is better for a cPanel server, or you like to use and the reason?

CPanel :: Var Partition Usage Warning

Jun 30, 2015

I have one dedicated hosting and it's just hosted of 100+ wordpress sites, I am very new to web hosting, previously my developer taking care all of this. But he was left the company few months ago.

Recently I had received few email alerts from my hosting service provider said that my /Var disc space already use up to 95%. It sounds very serious and make me worries that what will be happen if I do not take action. When I chat with the hosting service provider, they telling me that increase my disk space of /var is the only solution. But I not sure whether this is the correct way ....

My hosting partition disk space allocation as per below:

/home 230GB (Usage 136GB)
/temp 2.0GB (Usage 1.8GB)
/var 20GB (Usage 19GB)
/usr 20GB (Usage 11GB)
/boot 24M (Usage 157M)

From the above partition disc allocation, My questions are:

(a) Since I still have quite a lot of the disc space for my /home and why cannot move some disc space from /home to /var? Is it once the partition and disc space allocation is fixed during the set up, it cannot be change anymore?

(b) The above system partition allocation scheme is the standard way? What is the best partition allocation scheme?

(c) Currently my package is 300GB SATA AND 8GB Ram with 1TB Backup. My hosting provider offered me a FREE additional 1X300GB SATA to get me stay with them. I just wondered whether should i stay with them or move to other service provider. Currently I am paying monthly US$334-00 for a dedicated server and below is the specs:

Processor: Single Processor with 8 Core AMD Phenom II X6-1055T
Ram: 8G
Disc Space: 300GB SATA and ITB Backup
Bandwidth: 5TB (my monthly usage less than 1TB)

Data CPanel :: OS Reload To Reszie / Usr Partition

Feb 13, 2015

we have a server on and constantly keep getting the problem that our /usr partition is too small.Now we contacted and they said the only way to resize that partition would be an OS reload. Now here are a few questions:

1. Do you know of any other (better) way to resize /usr
2. If we do this OS reload mentioned all data would be lost. How do we best go about to backup the data (whole server I guess, including the current cpanel/whm configuration) and once the reload is done add the backup again so everything works like before?

We of course would like to have as less dowtime as possible.

Creating A New Partition

Mar 6, 2008

The server I got from LayeredTech has two hard drives, obviously they set up the first hard drive with Linux etc.

The second hard drive is just there, not showing any partitions in 'fdisk' when I checked, so I assume they just leave it blank in every new server for the owner to deal with however they want.

I've been looking up guides to create a new partition for the full size of the hard drive and then mount it. However, it hasn't been very successful. Everytime I created the partition in fdisk, I have to set a size, and then when I mount it, it only says that the drive is ~98MB big.

Is there a way to partition the drive to its full capacity? And then mount it somewhere on the system? Or anywhere I can go to to find out easily?

Resizing Partition

Apr 23, 2008

I recently ordered a new dedicated machine and for some reason the guys set it up so the /home partition is a massive 250GB, and the / partition is a tiny 20GB. Since that's where all the plesk domains will be storing their files, I'd like to resize things a bit. I'm thinking of making the / partition 200GB and the rest for /home

It's a CentOS machine and the filesystems are ext3.

How can I do this resizing, and are there any caveats I should be aware of?

Raid1 Partition

May 26, 2008

If this is not in the right forum for this... I'm sorry didnt knew where else it may go.

I have to build a new server with RAID 1 and WHM/Cpanel installed (in fact i dont have to, but i need to learn ASAP and my boss gave me an old server for practice).

I've seen the installation guide of cpanel but the sizes of the partitions apply to a disk of 80 GB (i think so) so is there any way to calculate the size of the partitions, regardless of disk size? cuz mine are of 250 gb each.

I'm trying to install it on centos 5 on text mode, so far i have been able to successfully install the system (with partitions of any size... since is a test doesnt matter) with RAID 1.

After that i ran cat /proc/mdstat and in some partitions shows me this


I've read in some places that this is not a big issue... but in other places says it is... maybe i did something wrong

But i would rather name is something normal like /dev/sda1

Is this possible with out losing any data?

If so how can this be done?

Way To Clean Up /boot Partition

Mar 14, 2008

I've got Centos 4 and I'm wondering what's the best way to cleanup my /boot partition?

Tried to do a yum update tonight and it included kernel, amongst other updates that belonged there so it stopped. I've googled around for commands to run and whatnot, but no go... or I just can't find it... if I had to clean it up I have an idea already about what to do, but I want to ask for advice first to see if there's an easier way.

so, how do people here clean up that partition?

PHP Work With Noexec Partition As Cgi And Others Cant

Jun 26, 2008

I have webserver running php with apache suexec and my /home partition is mounted with noexec in fstab.

My httpd.conf includes line like
Action application/x-httpd-php5.cgi /cgi-sys/php5.cgi
AddHandler application/x-httpd-php5.cgi .php

everything works perfectly. However I tried same configuration for python and perl and it did not work. But it worked if I mounted /home without noexec.

What makes php so special that it can work with noexec partitons as cgi while others cant? I would really like to know as I would like to run perl and python with noexec partitons.

Please dont discuss alternatives to noexec flag. This would be off topic.

/tmp Partition Dissapear After Reboot

Dec 13, 2008

I recently created a /tmp partition to get it secured to avoid file execution from that dir.

So, created a partition for tmp:

cd /dev/; dd if=/dev/zero of=tmpMnt bs=1024 count=1000000
mkfs.ext3 /dev/tmpMnt

Then mounted the partition

mount -o loop,noexec,nosuid,rw /dev/tmpMnt /tmp

Configured /etc/fstab so the partition is mounted after every reboot:

[]cat /etc/fstab
LABEL=/ / ext3 defaults 1 1
LABEL=/boot /boot ext3 defaults 1 2
tmpfs /dev/shm tmpfs defaults 0 0
devpts /dev/pts devpts gid=5,mode=620 0 0
sysfs /sys sysfs defaults 0 0
proc /proc proc defaults 0 0
LABEL=SWAP-sda2 swap swap defaults 0 0
LABEL=/tmp /dev/tmpMnt ext3 loop,noexec,nosuid,rw 0 0

[]df -ah
Filesystem Size Used Avail Use% Mounted on
/dev/sda3 224G 3.1G 210G 2% /
proc 0 0 0 - /proc
sysfs 0 0 0 - /sys
devpts 0 0 0 - /dev/pts
/dev/sda1 99M 21M 73M 23% /boot
tmpfs 1014M 0 1014M 0% /dev/shm
none 0 0 0 - /proc/sys/fs/binfmt_misc
/dev/tmpMnt 962M 18M 896M 2% /tmp

[]ls -alh /dev/tmpMnt
-rw-r--r-- 1 root root 977M Dec 12 18:00 /dev/tmpMnt

Now, after rebooting the system the partition is no longer there?? (and of course, not mounted /tmp due to this)

[]ls -alh /dev/tmpMnt
ls: /dev/tmpMnt: No such file or directory

This was done under a plain RHEL 5.2 box.

Optimal Partition Setup

Apr 13, 2008

I just purchased a dell poweredge in order to move my website to its own dedicated server. I have a few questions on the best linux partition setup for a webserver. The system has 8 gigs of ram, raid 10 setup with four 15k rpm drives and two quadcore cpu's.

The os is CentOS 5.1

The server can have up to 30,000 uniques in a single day and can be somewhat database intensive.

Does anyone have a recommend partition setup, besides the default?

With 8 gigs of ram, what is the recommend swap? I've seen rules that say anything over 2 gigs of ram, the rule is S = M+2. So that would put me at 10 gigs swap. Is that overkill?

Should i make a seperate partition for log files?

Partition Sizes Layout

Aug 10, 2007

I have a dell 2950 server with raid 5 + a hotswap.

There are 4 73G 15K drives with TWO dual quad process.

4G mem

I was reading that the swap space s/b 2X the mem or 8Gigs.

The swap drive should be at the outer edge of the drive for speed.

Or drive C, but with these fast drives is it really going to matter

My layout idea so far is as follows

8 swap
20 OS and programs
20 SQL databases and websites
10 log files
10 downloads and upgrade files.
