RustFS on OmniOS

[guenther-alka]

I am on Illumos/OmniOS, an OpenSolaris Fork (Unix). This is one of the most minimalistic server lts operating systems for production use with quite the most stable free ZFS included in its native environment. OmniOS has MinIO in its repository and I included it in the past in my napp-it storage web-gui for any OS (Free-BSD. Illumos, OSX, Linux, Solaris and Windows).

RustFS Binaries are not available for Illumos so I tried to build myself. It took me many hours with the help of Claude. Not sure if RustFS is interested to make the build process easier or to offer an Illumos binary

To start RustFS on OmniOS I had to increase ip settings to start RustFS

ipadm set-prop -p max_buf=4194304 tcp
ipadm set-prop -p max_buf=4194304 udp

Then I tried to connect webconsole on https:/ip:9001 and got 404
From WinSCP the folder on the S3 Storage (on ZFS) looked similar to Linux or Windows

Any hint?

just an update
the problem persists with beta3

Update:
the RustFS S3 server on OmniOS is working, it is just the webconsole that does not work.

How to test and a workarounf for missing webconsole:
Open WinSCP and create a tab for S3, your OmniOS ip:9000 and credidentials
Prior opening the tab, use Edit Tab Settings -> Advanced and set path mode for buckets under S3 (instead default virtual host https://bucketname.site.xx)

Assisted by Claude, I could finally create a build script for 1.0 beta8
(took me days due ~1h build time) that reflects needed modifications to run current RustFS on Unix/Illumos

RustFS 1.0 beta 8: ok
RustFS webconsole: ok (tested login)
rc management tool: ok
rclone: ok (rsync for cloud)
restic: ok (backup restore with encryption, snaps and dedup)
acl save/restore: ok
any OS save/restore: ok (ZFS snap based, also Solaris <-> Illumos/OpenZFS)

needed modifications

aws-lc-rs ? ring (Illumos has nok pthread_rwlock_t with -std=c11)
mimalloc deactivated (SIGSEGV during Initialisation)
allocator_reclaim.rs illumos no-op
jsonwebtoken rust_crypto Feature (JWT Auth)
pulsar build.rs stub + proto stubs
brotli alloc-no-stdlib 2.0?3.0

Console v0.1.7 embedded -> http(s)://ip:9001
