UNIX for Dummies Questions & Answers

I have been told to look after a server running Sol9 with the following structure:

c1t0d0s0 65G /
c1t2d0s7 67G /usr
c1t4d0s6 24G /var
c1t3t0s7 67G /home
c1t4d0s7 14G /opt
c1t4d0s5 29G /tmp

This server is used to hold tool installations and as a license server for EDA design tools with around 20 users max.

Is it OK to put the tool installations on the root partition, or should I use a separate partition for this?

Many thanks,

SteveO.

You really should not have any of your 'own' stuff on the OS disk. The best thing to do would be to have two 9GB disks (which would have /, /usr, /var and /opt) as mirrored OS disks (this would be more than enough) and then have everything else on different partitions.

I thought that having own stuff on / partition was a bad idea, but could not remember where I had seen this.

'Scuse my ignorance though - can you explain mirrored OS disks?

the op has 4 72 gb drives in the server so putting in 9 gb drives would be regressing ...



anyways ... smo ...

1. is this partition scheme already installed in the server and cannot be changed or is this still in the planning stage?

2. how big are the data and/or log files generated by the tools application? how quickly do they accumulate?

3. how long are you folks intending to keep this server?

This is the scheme already installed by my predecessor. I am happy to move things about if it is safe and easy to do so.

Not sure I'm afraid.

At least 6 months. After this time we will probably review usage and see if we need to change anything.

on the assumption that ...

1. the design tools app will be taking up huge globs of space
2. you need to have ready access to the data
3. you have network-based backup
4. the server is specifically for the design tools app only
5. tools data will be deposited in a central directory
6. some users will be putting in their temp work files as well as data in their home directories
7. c1t0d0 and c1t2d0 are disk0 and disk1 respectively
c1t3d0 and c1t4d0 are disk2 and disk3 respectively

c1t0d0 and c1t2d0 are formatted the same way and mirrored with Disk Suite
c1t4d0 and c1t4d0 are formatted the same way and are either concat to make a 136G filesystem mounted on /export/data or mounted separately into /export/data/ and /export/data1 or mirrored and the mirror mounted on /export/data
there is a lot of space in this server --- i just put in what i thought would be useful if this was my server and if i had a need to use all the disk space ... otherwise, i'd remove 2 drives and confgure the server with just the 2 remaining drives mirrored ... home and data would be in /export so i only need to specify /export to be able to backup all the non-system data files ...

Thanks JustIce,

One problem I am having is that I am unable to specify a partition called "/export".

Whenever I go through format, I am only allowed a few specified tags (/usr, swap etc. I think.)

When I do a "mkdir /export", this is added to the root partition. Any idea how I can create my "/export" partition?


Thanks again,

Stephen.
