Re: [9fans] I did bad things and 9front won't boot
At a guess, you tried to run something like: mount /dev/sdXX/cache which will try to negotiate a version with your raw disk data, and write a Tversion message to the first block of your disk. You want to mount the 9p service which lives in /srv/cwfs. You can probably either write it back manually, or using the fs recovery console, documented (er, kinda) in fsconfig(8). For reference, the fsconfig should look like: filsys main c(/dev/sdN0/fscache)(/dev/sdN0/fsworm) filsys dump o filsys other (/dev/sdN0/other) noauth newcache blocksize 16384 daddrbits 64 indirblks 4 dirblks 6 namelen 144 cpu% read -c 1024 /dev/sdN0/fscache service cwfs filsys main c(/dev/sdN0/fscache)(/dev/sdN0/fsworm) filsys dump o filsys other (/dev/sdN0/other) noauth newcache blocksize 16384 daddrbits 64 indirblks 4 dirblks 6 namelen 144 Quoth o...@o5r.ca : > Hello, > > I seem to have done incredibly stupid things to my 9front instance and now on > boot I get "panic: unknown keyword in config block: ", > followed by a "mount: sys: write on closed pipe pc=0x2008c6" and "mount > /srv/boot /root: mount 185: sys: write on closed pipe pc=0x2008c6”. > > At this point I did try to drop into a shell, but I can’t figure out from > there how I can mount my filesystem (that I can see in the list of things > under /dev/sdE0/fsmain). > > By now I’ve also figured out that the panic is happening “here”, in the > mergeconf function: > http://git.9front.org/plan9front/plan9front/858893ff8ff8d3abd06742276bcb794f3422bab8/sys/src/cmd/cwfs/config.c/f.html > > Is there a way for me to rewrite the config block to sensible defaults by > dropping into a shell and/or using a usb drive w/ 9front on it (as if doing > an install) to just backstep whatever terrible thing I performed accidentally? > > Thanks, > > Olivier -- 9fans: 9fans Permalink: https://9fans.topicbox.com/groups/9fans/T110553196be52532-Mea1e17036a202917e1169d92 Delivery options: https://9fans.topicbox.com/groups/9fans/subscription

See also fsconfig(8) [2]. What you enter here depends on your setup. You may want to subscribe to the 9front mailing list [3] and ask 9front-specific questions there to get better help.

[9fans] I did bad things and 9front won't boot
Hello, I seem to have done incredibly stupid things to my 9front instance and now on boot I get "panic: unknown keyword in config block: ", followed by a "mount: sys: write on closed pipe pc=0x2008c6" and "mount /srv/boot /root: mount 185: sys: write on closed pipe pc=0x2008c6”. At this point I did try to drop into a shell, but I can’t figure out from there how I can mount my filesystem (that I can see in the list of things under /dev/sdE0/fsmain). By now I’ve also figured out that the panic is happening “here”, in the mergeconf function: http://git.9front.org/plan9front/plan9front/858893ff8ff8d3abd06742276bcb794f3422bab8/sys/src/cmd/cwfs/config.c/f.html Is there a way for me to rewrite the config block to sensible defaults by dropping into a shell and/or using a usb drive w/ 9front on it (as if doing an install) to just backstep whatever terrible thing I performed accidentally?
