From 53950ef541675df48c219a8d665111a0e68dfc2f Mon Sep 17 00:00:00 2001 From: Martin Brandenburg Date: Tue, 25 Apr 2017 15:38:04 -0400 Subject: orangefs: do not check possibly stale size on truncate Let the server figure this out because our size might be out of date or not present. The bug was that xfs_io -f -t -c "pread -v 0 100" /mnt/foo echo "Test" > /mnt/foo xfs_io -f -t -c "pread -v 0 100" /mnt/foo fails because the second truncate did not happen if nothing had requested the size after the write in echo. Thus i_size was zero (not present) and the orangefs_setattr though i_size was zero and there was nothing to do.
