My colleague says . On some boxes we have /var/,/opt are inside root and on some they are not on root they are separately. So please any one explain me what actually the difference is.
In Windows, each drive letter is its own seperate little world. c:\ gets you files under partition 1, d:\ gets you files under partition 2, etc.
In UNIX, all files and partitions are accessed through the same directory tree. The root partition is attached first, at /, and other partitions can be optionally attached to any directories inside /, even ones inside other partitions.
So the root directory exists on the partition /dev/sdc3. If you created a file /randomname, it'd go into sdc3.
"udev" and "shm" are special filesystems handled by the kernel, you can ignore them for the moment.
Anything under /home/ goes into sdc5, so all user directories reside on that partition.
Our mysql database used to reside inside under the /var/ partition, in /var/lib/mysql, but it outgrew it. I had to give /var/lib/mysql its own partition so mysql would have more room.
You have the above mentioned partitions but as per my knowledge we can just have seven slices in a disk .If that's the case how can we accommodate all the above mount points.

Maybe that's true for SPARC based systems, I don't know. Mine is a PC system with an old-fashioned MS-DOS boot sector. That only supports 4 partitions, but any of those can be an "extended" partition that holds other partitions. Like so:

Partitions 1 through 3 are regular partitions. Partition 4, the very last partition I'd be able to fit in the table, is an "extended" partition which holds other partitions: sdc5, sdc6, sdc7, and sdc8 actually reside inside it.
This is architecture-specific and OS-specific, don't try fdisk on a solaris system -- it's either absent or something completely different.
What isn't OS and PC specific is what you can do with the partitions once they've been made: Attach them wherever you want in your file tree.

I had a query as to what are the partitions that should be necessary in RHEL 6. My knowledge says that
1) /
2) /home
3) Swap
4) /boot
should be sufficient. But, I am seeing in my production environment which is RHEL 5 that there are partitions also for
1) /var
2) /tmp... (8 Replies)

I'm trying to find out how many logical partitions our AIX box has. I'm running the command: topas -C
and nothing is showing up. Is it safe to say that there is only one LPAR, which is what AIX is installed on?

I have a partition that due to some automated processes can fill a partition to 100% before the weekly backup and cleanup process happens. Is there a way I can monitor a partition and send a page or email if the partition gets above 85% full? (2 Replies)
I have a partition that sometimes grows to 100% before the weekly backup and perge can happen. Can someone leade me to a script that will monitor the size of a partition and send me an email when it is over a certain percent? Unix Solarus 8.
