No. We rarely (I have seen it only twice in the last two months) observe instabilities of the rump-based file-system server. Once this happens, you may try closing the inspect window (by disabling all 'inspect' buttons), and then opening the inspect window for the ram fs (which should not be affected). Then you can inspect the '/report/log' for file-system-related error messages. It would be cool to secure the log should encounter the problem again. I'll try to replicate it. Wish me luck.

Hi Guido, thanks for the prompt feedback and the thorough testing! We might update the downloadable image once we update our master branch next time. > Other news: > 1.

Supposing you were testing this with the RAM fs, the jittery effect may be caused by the successive expansion of the RAM file system.

I forgot to sent this to the list for everyone, not just the spooks who tapped the line ;-) On 06/21/2018 01:51 PM, Norman Feske wrote: Hi Guido, thanks for the report and the log. I have a faint suspicion. could you please give the following image a try? http://genode.org/files/nfeske/sculpt-2018-06-21.img Hi Norman, Your hunch was correct, this image runs the expand process correctly on my 'bad' stick. I ran it three times just to make sure, both in usb2 and usb3 sockets. All good. Other news: 1. I noticed that the debian iso-download on this 06-21 image was jittery, stopping the now-counter for a second every few MBs. Is that an effect of these patches? 2. With the old (sculpt-tc) image, the debian download sometimes hang with what looked like a filesystem lockup. I could not save the config/deploy, nor exit vim. Other processes seemed unaffected. Is that lockup to be expected from the old code? It could also have been a memory error I encountered with memtest. But that was transient. I could not pinpoint it to a single DIMM, nor did it occur any time after that. Perhaps this iron is getting old and flaky. Anyway, thanks for the patch. I've attached the log.

Hi Norman, I've tried again with the same stick and the hang is reproducable, as well as the trigger to restart by plugging a different stick as well. I installed sculpt-tc on that newer stick, booted it and the expand worked first time! Thanks for your offer for a debugging image but I think I don't need it anymore. If you want to test your suspicion, I can run it with the bad stick and provide you the log. Thanks for the push to try again. Now the download-errors Cheers, Guido. ___ Genode users mailing list users@lists.genode.org https://lists.genode.org/listinfo/users

My experience with the official release of Sculpt TC
Hi Genodians, I tried this version too. It has some visual differences: - the network-section has these buttons: Off, Local, Wired. While the 18.05 version had Off, Wired, Wifi. There is no mention of Local in the Sculpt article. The Expand option of the GENODE-partition hang at first with an error: [runtime -> usb-1-2.part_blk] Error: Block-session creation failed (ram_quota=4208640, cap_quota=5, tx_buf_size=4194304, label="") [runtime -> usb-1-2.part_blk] Error: Uncaught exception of type 'Genode::Service_denied' When I plugged in a second USB-stick, the resize proces restarted and delivered a bootable resized stick. In case you're interested, I attached the LOG of that session.

Official release of Sculpt TC
Hello everyone, I'm happy and proud to announce the official release of the second incarnation of Sculpt OS. Sculpt for The Curious can be downloaded as a ready-to-use disk image: https://genode.org/download/sculpt The downloadable image is a live system, rescue OS, and installer all in one. Compared to earlier versions, it features a graphical user interface for common tasks like connecting to a wireless network. The actual fun happens in the text-based user interface of the "Leitzentrale", which empowers the user to shape the system live, and to inspect the system's state at any time. For detailed usage instructions, please refer to the accompanied documentation: https://genode.org/documentation/articles/sculpt-tc Cherrs Norman -- Dr.-Ing.
