Re: New kernels

Post by Hypex »

I was hoping to test some new kernels but got a bit stuck. I merged my Ubuntu Xenial with my Fienix partition to give it more space. After backing up files. But it failed when I tried to create a new volume for Fienix. I had over 20 partitions and maybe stuck on SCSI device 16 limit. I recently found I couldn't mount any volume after the limit. Which seems ridiculous as I still have 250GB space on the end of my drive which is unheard of with most of my systems. Perhaps Xenial is compatible with v6 kernels, I should test that. Keep me going in the meantime. :-)

FYI: journalctl -k -b -1 gives logs from previous boot.

Okay, so it looks like a limitation placed on the SCSI subsystem, which is inherited in the sda devices scheme. So, SCSI devices can only have max 16 with max 16 partitions. While IDE, which once used the hda scheme, can have max 64 partitions. Which looks ridiculous. As pointed out, regardless of Linux for some reason taking SCSI and using it (like on Amiga) as a storage device convention SCSI said nothing about any partition layout.

https://askubuntu.com/questions/350358/ ... f-12-04-on

https://superuser.com/questions/944112/ ... partitions

I was about to add volumes in Disks beyond but then it gave me an error creating it. I could only create extra partitions in Media Toolbox and format in Disks. Indeed, I discovered this when trying to mount a /dev/sda22, which happened to be in FFS and it couldn't mount on the device point.

When using amiga-fdisk it too refused to work with it and gave me errors of RDB 16 partition limit. I've never heard of this limit before in Amiga. Given you can format a drive with GPT which has 128 partition limits and can only max it out at 16 in software proves there is something wrong with the Linux device drivers. Neither SCSI nor RDB places these limits on the disk partitions but somehow, for some historic reason, Linux does.

I can't find the link now but I read by specifying cylinder alignment on RDB disk can circumvent this limit and can confirm that also can work.
