VM disk for OS (Debian 12.x) gets smaller and smaller - NOT the same disk i used for .bitdoin data directory which is mounted on another disk

I ask me why? Now i added the txindex=1 option to bitcoin.conf file and it’s the OS disk that gets smaller and smaller - NOT the disk where .bitcoin data directory is located… that’s very, very confusing i.m.o

B: = bitcoin data disk where .bitcoin data directory is I: = disk where the virtualbox bitcoind VM (Debian 12.x) is.

maybe it saves tons of logs in /var/ log ??

We can’t help you by guessing what you did and what went wrong. You’ll have to explain everything in detail.

Make sure to fully read https://github.com/bitcoin/bitcoin/blob/master/doc/files.md and understand it, first.

Bitcoin core itself doesn’t write anything to /var or anywhere but the data directory. Of course, it may be that some other process is doing that. You’d want to figure out what files use the disk space. i don’t know what’s a good tool for that in windows but in Linux you’d typically use du -h.

On Windows you can just right click and the Properties dialogue should spit out the folder size, IIRC? (Haven’t used it in a decade). But yeah, without more details, there is nothing that can be done here.

bitcoind is not (directly) on Windows 10 (pro, x64) - the screenshot just shows the drives used by my bitcoind Debian 12.5 virtual machine.

since i added “txindex=1”, the drive B:\ where ~/.bitcoind linux mount point saves its data, free space decreased NOT, while I:\ drive (where the debian 12.5 os is, the rest, excluding ~/.bitcoind) space decreased rapidly… ca. from 40gb left to 3.7gb left

My implication: bitcoind does not only save its data in ~/.bitcoin directory (“data directory” where the blockchain is)…

Well you can look at it, presumably? How much data is in the ~/.bitcoin directory? If it’s empty, perhaps there is a configuration error and some other directory is used as datadir?

the bitcoin application directory seems to be also very big… now i’m confused, i was thinking the bitcoind saves all its volatile data in ~/.bitcoin [data] - not in ~/bitcoin [application]

Here the drive / mount point used for ~/.bitcoin (data) symlink

/dev/sda1 1054729716 650342244 350736480 65% /mnt/btcdrive

Inside the VM, what do you get if you type ls -l ~/.bitcoin?

The contents of ./bitcoin is presumably just your compilation artefacts. They won’t change unless you build again, and aren’t needed beyond the binaries in it (bitcoind, bitcoin-cli, …).

Thank you very much - will look on it ASAP

(Now the VM is completely fu**ed up, because of 0.0gb left, need to do some steps now)
