One of our server is very slow and cpu and memory usag is fine. Also, there isn't any problem on network, I thought the problem with disk and I got the following iostat result. Is it normal?

My server has a small SAS disk(about 73G), if I use 90% diskspace of it, is it good idea, will it harm the physical HDD?
View 6 Replies View RelatedI am looking for better disk performance. Due to the tight budget, I have to choose one of following options as my disk choice:
2 SATAII disk w/RAID0, 7200rpm, 32M cache for each disk
1 SAS disk, 15000rpm, 16M cache.
which one will be better and how better if other things(hardware & OS) are same?
can a Xen disk image be converted to a diskpartition?
Someone is asking whether I can host his disk image at his current host, which he is leaving for poor I/O (wonder why that would be ). I can host a diskimage, but I don't like diskimages (slow, and 100GB isn't very 'comfortable' either). Is there any way out there to convert a disk image into a normal partition?
I wonder why the USA used to give to the servers, only one disk? from my experience with the most disk malfunction occurs and the immediate unavailability of the server (and, if sufficiently intensive and does not lose data). Or is a solution which I have noticed, and they use it?

As you can see, I have used approximately 1.4GB of the 74GB, but regardless what kind of funky math I do, I seem to be missing about 3.5 GB or so. I know there might be 2GB as swap (which I'm not seeing listed, but it should be on a different partition not listed so it should be fine), even then, where's the remainder 1.5G
I use apache with CentOS VPS hosting for my blog. I only host one blog in this VPS account. I have 1.5GB RAM and I have 7, 500 page preview per day. My page loading time is 2-3 seconds (according to the pingdom tool).
I want to know what is the best performance (faster web page loading) W3 Total cache option for VPS hosting blog. Currently I use Disk to enhance for page cache and database cache for disk.
it took me one year to develop the disk cache tool which can dramatically boost your host and save your harddisk. it is like supercache,but more cheap and better speed.
check picture to see what it can do.
i will offer free download to test the tool by first 10 people. if u host huge traffic website, do not hesitate to try it. i already test it for half a year. it is time to publish it. pm me or post here to get free download.
i open to any opinion about the tool.
How much estimated free space should one have on a Fedora 5, Cpanel server with 80GB drive after installation?
View 1 Replies View RelatedMy server hard disk is crashed badly. The rescue function in the server cannot take part and so I've tried using some recovery software to get back my data.
I've tried using Easy Recovery Professional. It sort all the files by it file type into different folder. I found a folder named .DB, there are also some .ado and . ldb folder too. I guess one of it is my database. The problem now is, i dunno how to read the file.
Do you have any idea to read it? I've tried many recovery system. eg. DiskInternals Linux Recovery, Disk Doctor Linux Recovery.
it is a linux server

I'm about to purchase a 2nd server to be used as a database/app server alongside my current server (of which will be the web server).
I wish to use 2 x 146GB 10K SCSI hard disks (in RAID 1) on the database server, but will be keeping 2 x 320GB SATAII 16M in RAID 1 on the web server. Will the SATA hard disks affect the performance / effectiveness of the SCSI disks or will I benefit from SCSI even though they're only in the database server?
Also, I'm going for 10K hard disks over 15K because they $20 per month cheaper and it's already expensive ($150 p/m for the two 10K or $170 p/m for 2 x 15k). Taking into account the already hefty price, is it worth the extra for 15K?
We have a questions for everyone and any help would be greatfull, we are looking to limit disk inodes on a per user basis or server wide. we would like to know if anyone ca referance us as to how this is accomplished.

I have a server with two hard disks.
The centos operating system and plesk (and also apache webserver) are installed on the first hard disk.
I have mounted the second hard disk (6 TB with ext4 file system) in a folder under /var/www/vhosts/AHostingAccount directory.
This folder is accessible via plesk's file manager but i cannot access it via ftp.
I have a new CentOS 7, with Plesk 12, CentOS 7 by default has XFS filesystem.
I try migrate sites from another Plesk Server but Plesk agent say: "hard disk quota is not supported due to configuration of server file system" (my CentOS 7)
My CentOS7:
CentOS Linux 7.0.1406 64 bits
Plesk 12.0.36
My fstab
[root@ns ~]$ cat /etc/fstab
/dev/mapper/centos-root / xfs defaults,usrquota,grpquota 1 1
UUID=ba391bd5-786c-4ae7-8bbd-f36f831ae6eb /boot xfs defaults 1 2
/dev/mapper/centos-swap swap swap defaults 0 0
I added "usrquota,grpquota", then mount -o remount / ; but when I try quotacheck -fmv / I gest this:
[root@ns ~]$ quotacheck -fmv /
quotacheck: Skipping /dev/mapper/centos-root [/]
quotacheck: Cannot find filesystem to check or filesystem not mounted with quota option.
but quotaon command works:
[root@ns ~]$ quotaon /
quotaon: Enforcing group quota already on /dev/mapper/centos-root
quotaon: Enforcing user quota already on /dev/mapper/centos-root
The problem here is why Plesk does not recognize quotas as enabled on CentOS 7??
If I try this command it seems good:
[root@ns ~]$ /usr/local/psa/admin/sbin/usermng --isquotable
0
Also I do this:
- Disabled Selinux
- Check all packages as quota, etc.
I have been using some reference: [URL] ....
Under Service Status, the "Disk (dev) 100 % ", what should I do?
FreeBSD with cPanel installed.
My server load is high, i checked and see everuthing is ok.
I think my sata disk cannot support my hard disk traffic.
Is it posible to check wich file used more hard disk traffic? (rpm speed)
how can i reduce this value
it was at 70% but after i did wget for abig backup and its failed i get this value in dev/sda5

As per this [url]tutorial to set up disk quotas u need the /Home in the fstab file but how ever all i can find on my server is this:
LABEL=/ / ext3 defaults 1 1
LABEL=/disc2 /disc2 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-sdb2 swap swap defaults 0 0
LABEL=SWAP-sda2 swap swap defaults 0 0
How do i go about setting quota for my users
shared hosting env?

vm.dirty_background_ratio = 20
vm.dirty_ratio = 60

I have a VPS that has hard limits for Disk Inodes at 500,000. I am currently over 430,000.
I am only using 24GB of 40GB of disk space.
How do I find what is gobbling up disk inodes? How can I find unused, abusive or unnecessary disk inodes and remove them?
# df -i
Filesystem Inodes IUsed IFree IUse% Mounted on

From the Disk I/O performance is it better
1) to have main PHP file with 10 includes
2) all 11 files as one file
3) the difference is not big
Suppose
a) a low traffic site
b) a high traffice site
I have a server with cpanel/WHM. The file system says I am using 26GB of my 40GB:
Filesystem Size Used Avail Use% Mounted on
/dev/sda1 40G 26G 14G 66% /
none 257M 0 257M 0% /dev/shm
/usr/tmpDSK 243M 4.1M 226M 2% /tmp
/tmp 243M 4.1M 226M 2% /var/tmp
however the total of my accounts is less than 5GB.
How can I find out where all the other disk space is being used?
