ghettoVCB and esxi 8.0 "Operation not permitted"

[ArchParks]

ghettoVCB worked fine with esxi 7.03 (after changing the line that said 7.0.0|7.0.1|7.0.2|7.0.3) VER=7; break;;)

After loading esxi 8.0 this morning, it now says "-sh: ghettoVCB.sh: Operation not permitted"

Any ideas?

I just took a look at this in my env as it looked a bit strange. Because the script doesn't have interpreter specified at the top of the script by default (e.g. #!/bin/bash), it fails to run.

ESXi doesn't have fully bash, but it does have ash and if you add:

!#/bin/ash

as the very first line of the script, it'll run without issues.

I tried that and I get the same error. I even tried a small file that says nothing but:

!#/bin/ash ls

and it gives the same error.

If it has executable flag, you should be able to run it using ./ghettoVCB.sh or whatever full path. I confirmed it with a vanilla installation of ESXi 8.0

Because of the missing #! entry, it thinks the script is a binary and by default in ESXi 8.0, the execOnlyInstall parameter is enabled by default and hence preventing it from running.

Weird: ls -lh /vmfs/volumes/53ace301-ce670a12/batch/ghettoVCB.sh -rwxr--r-x 1 root root 70.5K Oct 13 13:21 /vmfs/volumes/53ace301-ce670a12/batch/ghettoVCB.sh

/vmfs/volumes/53ace301-ce670a12/batch/ghettoVCB.sh /bin/ash: /vmfs/volumes/53ace301-ce670a12/batch/ghettoVCB.sh: Operation not permitted

If I copy it to /tmp, it does this:

ls -lh /tmp/ghettoVCB.sh -rwxr--r-x 1 root root 70.5K Oct 13 13:48 /tmp/ghettoVCB.sh

/tmp/ghettoVCB.sh

/bin/ash: /tmp/ghettoVCB.sh: Operation not permitted

Note this was an upgrade from version 7.03.

Does /bin/ash show when you do ls? You could also try /bin/sh and I ended up using that to fix it in main script, which you can download directly from repo

Bear in mind that you know more about this stuff in your little finger then I do in my entire person so some of my comments are problem dumb!

I'm not positive what your first question meant but I tried changing the first line to "!#/bin/sh" but it gave this message: "/bin/sh: /tmp/ghettoVCB.sh: Operation not permitted"

for the heck of it, I ran this:

/bin/sh /vmfs/volumes/53ace301-ce670a12/batch/ghettoVCB.sh

and your script fired off (it gave the normal error saying " ERROR: Incorrect number of arguments!" because I didn't have anything else on the command line.

I then tried running it like normal with this command /bin/sh /vmfs/volumes/53ace301-ce670a12/batch/ghettoVCB.sh -f /vmfs/volumes/NFS/scripts/vms_to_backup -g /vmfs/volumes/NFS/scripts/ghettoVCB.conf -l /tmp/ghettoVCB.log

And its plugging away doing backups as I type this!

Thanks!

Last question: In /etc/rc.local.d//local.sh I have a line that populates crontabs by saying"

/bin/echo "55 19 SUN /vmfs/volumes/53ace301-ce670a12/batch/ghettoVCB.sh -f /vmfs/volumes/NFS/scripts/vms_to_backup -g /vmfs/volumes/NFS/scripts/ghettoVCB.conf -l /tmp/ghettoVCB.log > /dev/null" >> /var/spool/cron/crontabs/root

Do I need to change it by adding the "/bin/sh" portion at the beginning of the command that gets stored in crontabs or does crontab execute it like it did in version 7.0x?
