/home not recognized after hardware change

Ok, I'll read up on it. Thanks -

I will show this as solved.

Thanks again guys -

You can convert ext2 to ext3 or ext4 without reformatting and reinstalling.

Doh! Windowsy way-of-thought remainders....

If it's "only" journalling, will there be any performance gains?

And, to go from ext2 to ext4 would be a two-step process, correct?

Hondo,

when you have done the conversion, do not forget to change also the fstab entries from ext2 to ext4

I'd like to switch to ext3 but am a bit apprehensive with this (still feeling a bit numb from my last fubar experience).

Boot a PCLinuxOS liveCD, open a terminal, su to root, and enter the command;

[root@localhost ~]# tune2fs -j /dev/<whatever>                  <Enter>

Replace <whatever> with the actual device designation, first sda1, then enter the command again using sdb1. That will take care of converting both your / partition and your /home partition.

I successfully converted all of the partitions to ext3 -Thank You VERY MUCH O-P!

Hondo,

when you have done the conversion, do not forget to change also the fstab entries from ext2 to ext4 

Do I do that by just editing the fstab text?

Adding the journal (ext3) makes the filesystem much more robust, not particularly faster. Converting to ext4 gains some speed advantage as well. The conversion can be direct from ext2 to ext4 with a single command.

[root@localhost ~]# tune2fs -O extents,uninit_bg,dir_index,has_journal /dev/<whatever>          <Enter>

Very interesting, thanks Old-Polack.

Good to have someone that knowledgable around.

Ok guys, I have modded the fstab file to ext3.

Here's my next question though-

When I view the fstab file, it does not show the other partitions that are on the same drive as /home -

# Entry for /dev/sda1 :
UUID=e4c78aa0-44ca-4184-a8e6-3c6f25507570 / ext3 defaults 1 1

# Entry for /dev/sdb1

When I run the blkid command, it says-

[hondo@localhost ~]$ blkid

What do I need to add to the fstab file to include those 2 other partitions? (sdb2 & sdb3)-

[Hondo]

Disregard- I punted the 2 extra partitions, created a new one as ext3, and saved it to fstab.

Thank you all very much for your hep- I really appreciate it!

First you need to create a permanent mount point directory for each partition you wish to add to /etc/fstab.

Then you need to make the entry. As you have already labeled your partitions, why are you not using those labels?

Example:

Let's say you want to mount the partition with the LABEL="/WD-Storage" on /mnt/storage, the /etc/fstab entry would be

LABEL=/WD-Storage   /mnt/storage   ext3   rw,auto,exec,noatime    0 0

if you wanted the partition to be automatically mounted every time you boot your machine.

Note: In the /etc/fstab entry the quotes " are not used.

If you wanted to mount the partition as your normal user, at will, only when you need it, the line would be

LABEL=/WD-Storage   /mnt/storage   ext3   rw,user,noauto,exec,noatime    0 0

Thanks for the help O-P, but I'm a bit confused and having problems with my partitions (permissions).

Could you please give me a bit more guidance?

Here is the blkid output again-

I would like all of the partitions to be fully accessible/full permissions to my normal user (hondo) all of the time and still don't understand what I need to do.

The / partition permissions should not be changed... only root should have free access there. The partitions mounted on /StorageDrive and /backup can have their ownership given to your normal user with the following commands, while the partitions are mounted.

[root@localhost ~]# chown -R hondo:hondo /StorageDrive                <Enter>

[root@localhost ~]# chown -R hondo:hondo /backup                <Enter>

[Hondo]

Ok, I entered both commands in a terminal logged in as root (SU) and I still can't paste new files folders into those drives when logged in as my normal user.

I made sure that the drives/partitions were mounted too.

What am I doing wrong?

You're telling me a story about what you think you've done, but not showing the exact details of what you actually did. Try doing it again, but this time copy/paste the prompt, command, and output of the command, into your next reply, so we can see exactly what you see.
