single docker deploy: has no disks

Do you have physical disks assosiciated with your machine? Especially under /tmp (assuming you are using Linux). If that's not a problem could you post the output from lsblk?

The problem seems that the directory that is being created with $(mktemp -d) is not associated with physical disk, which is currently a requirement for running productionanized AIStore.

[shinexia]

the /tmp is under a mirrored lvm partition, so it is associated with TWO physical disks, not just one

on another pc, which root dir is not mirror lvm partition, has the same problem.

[VirrageS]

which root dir is not mirror lvm partition, has the same problem.

I'm confused as the lsblk shows ubuntu-root 253:0 0 476.4G 0 lvm /. Which is lvm partition.

[VirrageS]

Would you mind sharing lsblk -Jt output?

New aistore/cluster-minimal:latest image has been pushed out with the fix. Let us know if the issue still persists.

[shinexia]

thanks, now it's running.

[VirrageS]

Thank you! I will close this one. Let us know if you have further issues/questions :)

[TopTea1]

Hi @VirrageS, I comment on this issue because, with the latest docker image, I have the same issue. Can you help me with that ? Thanks
