Weird Problems

I/m having a hard time figuring out where is the OS volume?

It looks like i have 2 backup folders. 1 in /c and 1 in /backup. If i look inside both folders, they have the same folders and content? Frontview shows 1 share folder named backup..... I tried to mv -v dir1 dir2 /c/backup and got:

mv: `Commercial' and `/c/backup/Commercial' are the same file
mv: `DAG' and `/c/backup/DAG' are the same file
mv: `randy@lovenc.com' and `/c/backup/randy@lovenc.com' are the same file
mv: `Residential' and `/c/backup/Residential' are the same file
mv: `SDR' and `/c/backup/SDR' are the same file

Is 1 of the backup folders a symlink or something?

du -csh /backup/*
244G /backup/Commercial
42G /backup/DAG
45G /backup/randy@lovenc.com
399M /backup/Residential
6.1M /backup/SDR
330G total

du -csh /c/backup/*
244G /c/backup/Commercial
42G /c/backup/DAG
45G /c/backup/randy@lovenc.com
399M /c/backup/Residential
6.1M /c/backup/SDR
330G total

And i am not even sure /backup is the OS volume as the /backup folder is 330G and the OS volume is 4G.....

I guess i could mv the /backup folder and all contents to /c/some.other.folder and see what happens (i could always move the files back)....

And so i did mv the files as i stated above and then ls /backup = empty then ls /c/backup = empty. So 1 of these is a symlink of some type.

I'm waiting to hear back from 1 of you guys on how to identify where the OS volume is on the ReadyNAS Pro 4? It looks to be /dev/md0 from fdisk -l above but i wait to get specific instructions from 1 of you

/backup is a symlink to /c/backup

You can see this when doing e.g.

# ls -la /

Figured so but how do i identify where the OS volume is as i don't think i am even on the right volume?

I can take a look if you like. I've sent you a PM.

Whatever's not on the data volume or in some kind of tmpfs or ramfs or similar is in the root volume.

# cat /proc/mounts

gives a good indication.

You would ignore the directories /proc /sys and /dev and /run when looking for what's filling the root volume.

It takes some practice and familiarity to be able to quickly identify which is which.

It's much easier in tech support mode where when you mount the root volume everything within the mount point is data on the root volume as you haven't mounted other things within the root volume yet.

PM'ed you back

O.K.

It seems that Syncrify is starting before the data volume is mounted. So when the data volume is mounted to /c you can't see that there's 3GB on the root volume anymore.

Is there some way to have the data mount before Syncrify loads? We have had Syncrify running for at leats 3 years. Then we lost 2 drives in the NAS and had to reinstall syncrify.

Well another possibility is that you moved the Syncrify files whilst the data volume wasn't mounted to be beneath /c

If the data volume isn't mounted then moving files to be under /c will still leave them on the root volume and you won't see those files when the data volume is mounted in normal mode.

Just rebooted your system.

You know, i think thats exactly what happened..... I can't remember where i mounted the data volume but i bet is was on the OS volume then i moved the files. So is that something i need to redo or did you reverse it?

I moved the files over to the data volume.

So df /dev/md0 still shows:

Filesystem 1K-blocks Used Available Use% Mounted on
- 10240 588 9652 6% /dev

According to StephenB that should be something completely different. Where would you recommend i go from here? Reload the OS or fix the config?

Something is still wrong. I don't have any logs in frontview and when i click on download all logs, i get:

well, i was going to take a screen shot and post it but when i go back to frontview i get:

and nothing in frontview shows! This is what it was doing when the OS volume was full. 

You don't do

# df /dev/md0

But rather e.g.

# df -h

# df -i

One of the mounts shown will be a mount of /dev/md0
