I am using a HIGHLY modified install of Knoppmyth v4r5 (or v5r4 whatever makes sense)

The problem is the 2gb root partition is about full with all the extra plugins and dependancies I have been forced to add.

My question is this.

How best to extend this partition without losing anything. Backup is a huge issue as I am more or less can't. I do have a spare 20gb drive i can load in but it is not identical to the one in the drive. It is slightly smaller (about 20-30 clusters) so a direct drive clone does not work.

here is my drive topography.



hda3 is my live tv buffer partition. hda4 is used for composing dvd and can probably where I would like to steal disk space.

here is how my disks are filled.. Probably useless informatino but here it is anyway



Also, I would like to get my mysql databases and/or my logs off this filesystem since the DBs VERY corrupted when something blows up and the log files decide to fill up my root partition.

It's not at all uncommon to have some of the root directories (/usr and /home are common choices) on a separate partition in some distributions.

Have you considered moving /usr (your MySQL database is here) to /dev/hda4? This move would free up 1.5G on my system.

At the root, as root, issue the command

to see which root directories are taking up the most space. Pick one and move it. Much more sensible than extending the root partition, in my opinion.

I thought about that. Let me make sure i am doing this right and not missing any critical steps.

1: Move dvd burner data in hda4 to /myth/backup
cp -rp /myth/mythtvburn/* /myth/backup

2: delete hda4 partition

3: Recreate partitions (hda4=2gb and hda5=rest for example)

4: recreate filesystems

5: mount hda4 as /mnt/whatever and hda5 as /myth/mythtvburn

5: move dvd burner data back to hda5

6: move data from /usr (or whatever) to new /mnt/whatever

7: umound and remount hda4 as /usr

think thats about it

derrr hmm .. question can I make more that 4 partitions per disk in linux? Do i have to muck around with extended partitions? would it be better to use lvm to split the current partition? LVM would make it easier to move the partions around again in the future if need be.

thanks

you can't have more than 4 primary partition on any x86 os, but yes linux supports more than 4 partitions you just have to go to extended partitions.

Xsecrets

df -h --max-depth=1

my copy of df does not have that option. I assume you mean du.

also, am I correct in that /proc does not exist and does not really consume disk space. or is it that its rebuilt every boot.

would I even have to break the partition? couldn't i copy the directory in question to hda4 and hard link it to that?

Ok i did it. I moved /usr and now X will not start. Also, ivtv doesn't seem to be loading


I assume a permission isn't set properly somewhere even though i used cp -rp


The logs sayL



Here is info that NO LONGER appears in the log starting. there is alot more that usually appears but i dont think it is relevant.

ok I'm 90% sure the /usr partition isn't mounting early enough.. it tries to detect the card before mounting the extra partitions

how do i fix?

The only skill i employed in this fix was counting. I moved the S19Knoppmyth-tv link to S37Knoppmyth-tv after the S35Mountall script.

It workd

i can watch tv.

I can watch recordings.

but i cannot seem to delete them. the file goes away but the entry in the database stays. since i moved the database ive got something else to fix it looks like. Is it that im loading mysql too early now also?

enough kludging for tonight.. apparently mythtv .17 inserts the program data into the database but doesn't create a file when it tries to record a program without hardware. I am rebooting to test stuff.

It silently fails to the end user but leave a log entry saying to the effect "file doesn't exist leaving entry in database incase video drive blew up."

you need to "touch" that file to create it so you can delete it. sure the government didn't write this program j/k

...still rebooting. I hope its just the manditory mount scan of my vid drive. i have rebooted ALOT today.

i was going to say microsoft but i would have probably been banned from the forum and my ISP melted down by the DoS

Ahh rebooted. strange. it didn't continue recording the program stopped mid record

but anyway don't hurt me

although it does look like im talking to my self .....

blah. final question.. I will probably let you answer this one since its late, and work calls.

How are the rc directories executed? my box goes to initlevel 5 automatically. so are the rc folders executed as follows in order? or is there some multitasking going on?

rcS.d
rc1.d
rc2.d
rc3.d
rc4.d
rc5.d
<gui comes up and ready to rock>

Reason I am saying this is because my sql database is coming up late and going away early from what i can gather from logs. the program that didnt record above was because of a failed sql query that happened before mysql was ready for connections. mysql starts at s20 and mythbackend starts at s25 in rc2-5.

Also on reboot I am getting a couple of errors that appear to be coming from the rc5.d script



These errors may have been caused by something I did last night because thats when the errors started showing up. (before i ravaged the harddrive) I was installing java and projectx for the new mythburn. I also burnt a couple of dvds. Other than that I have no clue.

That's a lot of replies in a brief time... sorry I haven't caught up.

You're right, "du" is the correct command, not "df"

When I originally posted the suggestion, I wasn't anticipating that you'd mount /usr from /dev/hda4 -- I intended to tell you to move /usr to /dev/hda4, then create a symlink to that folder in root:

ln -s /myth/mythtvburn/usr /usr

This approach eliminates the need to modify fstab, and lets you keep all of your other mythtvburn stuff in place. It's also the most easily reversible, in case the approach doesn't work. Sorry for not being clear.

Now that you've done it, however, it should certainly work. I can't see any obvious faults in your approach, and your problems sound like permission problems.

(I'll be unwired and on the prairie for the next five days, sorry in advance for the impending silence on my part)
