is related to LU-9846 Overstriping - more than stripe per O... Resolved
Severity: 3
Rank (Obsolete): 9223372036854775807

 Description   

There is an incorrect assert in lod_ea_store_resize which leads to an LBUG with very high stripe counts.  (I didn't calculate precisely, but 1300 is OK and 1600 triggers the bug.)

The fix is trivial.  Patch forthcoming.

Hit this in sanity testing for SEL:

[Edit]

This was due to a bug in SEL, now fixed.  Whoops.
