Im trying to configure plot_over. My setup for the mounted drives in /mnt/bay#/serial#/.
when I configure plot_over with

##Chiagarden plot_over config file

#Dry run is enabled by default, to ease your mind. set to false, to actually use plot_over
dry_run=true

minimum free space in GB

min_free_space="200"

desired amount of disks with min_free_space

amount_free_disks="44"

comma-separated list of Plot Compressions levels that you would like to replot. Those will be (gradually) removed.

this example would replot to C18

replot_levels="0,1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,17,19,20"

Default parameter for your label. Can also be set in commandline.

label="CHIA"

If you didnt label your drives with chiainit, you can set a parent mount dir where your your chia disks are mounted in.

mount_dir and "label" cannot be used at the same time.

mount_dir="/mnt/"

Default parameter for your first subdirectory for plots in Disk. Can also be set in commandline.

subdir=""

maximum search depth for plot files - how many subdir levels should we iterate?

search_depth="10"

rescan every xx seconds. this is AFTER removal of plot files in one iteration is finished. it is okay to set this relatively low (30s)

interval="30"

set to a valid path or leave empty to disable logging. Ignored (set empty) when plot_over is run from systemd

logfile="./plot_over.log"

set to true to display the paths that are searched for plot files

display_search_paths="true"

This is the output

If i change the config to use

If you didnt label your drives with chiainit, you can set a parent mount dir where your your chia disks are mounted in.

mount_dir and "label" cannot be used at the same time.

mount_dir="/mnt/bay8/"

The out put is

Working as expected.

I have approximately 44 drives that are filled with c8 compressed plots that I want to replot
they are located in /mnt/bay8/ & /mnt/bay9-11/

how can I configure plot-over to read the list of directories past the first set of bay# folders that are under /mnt ?

Problem

This line in chiainit.py causes is_drive_mounted() to incorrectly report drives as being mounted when they are not.

Proof of concept:

I am trying to initialize /dev/sdb, which is not mounted, but /dev/sdba1 is mounted. The grep expressing matches /dev/sdba1, and thus reports that /dev/sdb is mounted when it is not.

$ drive="sdb"
$ if grep -qs "/dev/${drive}[0-9]*" /proc/mounts ; then echo 'FOUND'; fi
FOUND
$ grep -s "/dev/${drive}[0-9]*" /proc/mounts
/dev/sdba1 /mnt/jbod1/jbod1-00014KYV ext4 rw,noatime 0 0

This was on a Debian Linux system, so YMMV if you are using a different grep variant or have configured bash globbing differently.

Explanation

Typically an asterisk is used in bash with paths for globbing. Ie, if we consider ls /dev/sda[0-9]*, it would only list all of the partitions of /dev/sda since the expansion is occuring via bash globbing.

However, since it's the path is part of a grep PATTERN, instead of globbing, the asterisk is being used as part of the REGEX as a repetition specifier. The default REGEX engine used is BRE, which treats the asterisk as: The preceding item will be matched zero or more times. Thus the [0-9]* pattern makes the digit optional (ie, 'match 0 or more times'). It's effectively just looking for any entry in /proc/mounts that contains /dev/$drive.

Solution

To solve this, simply match one or more instead of zero or more:

• via BRE: grep -qs "/dev/${drive}[0-9]\+" /proc/mounts
• via ERE: grep -qsE "/dev/${drive}a[[:digit:]]+"
• via PCRE: grep -qsP "/dev/${drive}\d+" /proc/mounts

However, it's technically possible in Linux to mount a full-disk filesystem without a partition table (mkfs.ext3 /dev/sdb ; mount /dev/sdb /mnt/something). We probably want to also detect this, just in case! So something like this might be more appropriate:

grep -qs "/dev/${drive}[0-9]* " /proc/mounts

Note the addition of the space at the end of the PATTERN. That would only match the expected $drive OR any of it's partitions, but not any other drive whose name is a superset of our drive. And 1-character bug fixes are cool :)

Thanks!
