It shouldn't be terminating at this point, but I suspect a bug in llverfs and not in the filesystem. I _thought_ there was an llverfs(8) man page, but it turns out there is only an old llverfs.txt file. > (llverdev terminates with 'write complete' also, no errors indicated - > good?) You can restart llverfs with the "-r" option so that it does the read tests to verify the data, and the "-t" option is needed to specify the timestamp used for the writes (so that it can distinguish stale data written from two different tests). In hindsight, it probably makes sense from a usability POV to allow automatically detecting the timestamp value from the first file read, if unspecified, and then use that for the rest of the test.
