Hi there,

I would like ot use Debian box as iSCSI server (target if I'm not 
wrong). So I have two questions:


1. If I export /dev/md0 via iSCSI would I benefit from memory buffers?


That's an interesting question... in all environments I ever used it, 
network was the bottleneck, so even if there are scenarios where memory 
buffers may be useful, you'd need very good connectivity to notice them, 
I think.


I'm using ConnectX 3pro Mellanox adapters (56Gbps), it was cheaper than 
10Gb Ethernet.


2. Is it possible to export a virtual device (like vmdk) by iSCSI? 
This would allow slight overbooking of the storage space.


vmdk in particular I don't know, but I have exported overcommitted / 
thin LVs; for vmdk you might need to add some fancy losetup wrapper.


My experience with overcommitting block storage is not purely positive, 
so I'd suggest to be very careful ;-)


Ok, thanks

I've very little experience with iSCSI and don't know the answer to
this…

…just want to say that I use qemu-nbd to turn things like vmdk
images into block devices, which I can then do anything with that I
do for other block devices, so that might be an option.

Thanks for the tip. it seems quite natural idea to use virtual drives. 
Is there any tgtd "plugin" or "driver" with virtual disk support?

yes that would be acceptable,
given there is reasonable installation guide (debian-wiki,
usr/share/doc, ..) on how to combine and setup these packages

ok, i understand, 
i would be nice though to have something like forgejo

thanks for the feedback,

ps: i had been using redmine (debian, postgres) for more than 10 years
with dist-upgrades, which did the job well (with some quirks for git
and automatic repo creation to setup), so i was surprised to see it
disappear 
(i had to install a few gems that where not packaged though)

that is the installation part,
my bigger concern is the maintenance part over the years,
as many projects and git repos might depend on it,
what is your experience/suggestion with that?

It looks like it's just under-maintained. It's maintained by the Debian
Ruby Team, and perhaps needs more volunteers to work on it.

Although it did drop out of the Bookworm release, it looks like it was
subsequently added to the Bookworm 'backports' repository, so is
available that way.

Given the maintenance situation though, I'd not bet on it being in the
next stable release (it's currently not in the testing distribution).

thanks Juri, i would have to check gitolite3 setup with ldap/ad auth

for which purpose would you org-mode
(also given that devs can have their own coding style),

I heavily used MantisBT but it's only the bug tracking part

Do you try https://packages.debian.org/bookworm/fossil
