Mount Tmp As Filesystem

Jun 6, 2009

I currently have a VPS. I have installed cPanel/WHM + CSF Firewall.

Everything is fine and all the ports are closed except for the ones I need.

I currently have some issues I need to fix, but google isn't helping

Quote:

Check /tmp is mounted as a filesystemWARNING/tmp should be mounted as a separate filesystem with the noexec,nosuid options set

I tried googling this and there was a cPanel script but I do not have permission to run it. So does anyone mind explaining it to me one step at a time?

Quote:

You should consider adding ini_set to the disable_functions in the PHP configuration as this setting allows PHP scripts to override global security and performance settings for PHP scripts. Adding ini_set can break PHP scripts and commenting out any use of ini_set in such scripts is advised

I have disabled this in php.ini but I do not know why it still says that I have to fix this

Read Only Filesystem

Feb 26, 2008

I have a server with pacificrack. When I see my website it says "Read-Only File system" and my SSH dies with read-only file system errors.

It happens once per month, and the bad thing is I'm sleeping when it happens so I don't know my server is in this state.

Even though support fixes the problem within 15minutes of my support ticket, my server is down for hours because I don't know its down to then raise a ticket. I asked support why it happens and they never tell me... just tell me to read the logs but I'm not technical enough to understand linux logs etc.

Server is centos.

Filesystem Became Read-only

Jun 4, 2007

Somehow the filesystem on my server turned read-only. The databases would not connect. When I rebooted the box it would not come up.

Support had to run FSCK. Even after, the databases had to be repaired using the CPanel tool. Things seem to be ok now, however:

1. What could have caused this to happen? Software or hardware failure?

2. I get these notifications, should I be worried?

Ext3 On A Very Large Filesystem

May 23, 2008

We're considering deploying a large server that will have 8x 500GB drives in a RAID-10 config. I intend to use a 3ware 9650SE w/ BBU along with A/B power to each of the PSU's.

My question is... since this will return into a 2TB array/partition, in event of a crash (kernel panic, etc -- I expect a power outage will be very, very rare if at all) what do you guys think the fsck time would be? In my experience a RAID BBU significantly drops it, sometimes to the point of no manual fsck required, but in event of a manual fsck shouldn't the BBU be able to provide more consistent data (less errors) and therefore a much shorter fsck? Maybe just recovering the journal?

Postgres: Restoring A Filesystem Backup

Feb 19, 2007

i had to do a file system back up because of the size of my database.

i shutdown postmaster and tar'd the files.

i recently reloaded my OS and now i'm attempting to restore the backups. i first shut down postmaster, restored the backups to the data folder and restarted postmaster.

i then su'd from root to postgres user:

Code:
[postgres@austin1 pgsql]$ psql service_2_3
psql: FATAL: database "service_2_3" does not exist
DETAIL: The database subdirectory "base/16385" is missing.

the backups had a database named service_2_3 but upon restoring the backups, it doesn't seem to be available.

my data directory is /var/pgsql/data.

Code:
[postgres@austin1 pgsql]$ ls -lahR /var/pgsql/ | grep 16385
but that yielded nothing.

have i done something wrong while backing up? i don't think i have since i followed the postgres manual when backing up. but the administrators have not been very thorough with how they've set the system up for me.

how i can resolve this issue if you have the time.

Using Ftab To Mount?

May 4, 2009

I'm trying to mount a western digital external hd to a fedora core server. Does anyone know what I put in the file system line in /etc/fstab? I tried tmpfs but I couldn't see the files i placed there when I moved to a new server. I also tried vfat but that wasn't compatible. It couldn't read ext3 file system. Does anyone know what else I could try?

How To Mount And Use Multiple Drives

Jul 4, 2009

I must not even understand the basics of how mounting works in Linux.

Physical drive /dev/sda1 is mounted at /

I created a software RAID array (using mdadm) out of two other drives using mdadm, at /dev/md0, and mount it at /vol:

mount /dev/md0 /vol

Code:
Filesystem Size Used Avail Use% Mounted on
/dev/sda1 9.9G 2.2G 7.3G 23% /
/dev/md0 200G 470M 200G 1% /vol

Now I start creating files in /vol/*

Then I unmount /dev/md0

I still see the files at /vol/*. They seem to be on /dev/sda1.

So how do I use the RAID array at /dev/md0 that I tried to mount at /vol?
