I felt the footnote was an attempt at humour. It's true humour is difficult on an international forum.I actually find that inaccurate, aggressive, and slightly offensive. But not enough of those to make me report your post.As much as it pains me to say this, RonR is 100% correct in this thread, and the rest of you are missing the point (*).
(*) Possibly, intentionally so.
My previous contribution to this thread neither confirmed, denied, nor challenged the OP's experience or RonR's statements. I have not missed the point of it.
It's also not at all uncommon for threads to drift away from the opeing topic.
According to Wikipedia a loop device on Unix-like operating systems makes a file appear as a block device. See, for example,
https://en.m.wikipedia.org/wiki/Loop_device
The main thing needed is that the file appear as a stream of bytes which can be randomly accessed. Although the dataset record formats in z/OS do not fit this description
https://www.ibm.com/docs/en/zos-basic-s ... rd-formats
I feel there should be a way to create virtual block devices in z/OS as IBM invented the idea of a VM. Unfortunately, my mainframe experience ended with virtual punch card readers. Further discussion of z/OS would be drifting from the opening topic.
The observation here is CIFS provides files with the semantics needed to serve as the backing store for a loop device in Linux. It's possible, however, some older file servers may enforce a 2GB file size limit. That would make it difficult for a single file to hold a 16GB SD card image.
