Description

Update log failure shouldn't cause operation fail, because it's used for recovery, and there is still chance that operation can succeed, otherwise it may cause inconsistency in the system and cause some directories/files not accessible.

Below error message is seen:

Dec 13 16:10:41 vos08 kernel: LustreError: 7960:0:(llog_cat.c:597:llog_cat_add_rec()) llog_write_rec -2: lh=ffff9a2d43d99000
Dec 13 16:10:41 vos08 kernel: LustreError: 7960:0:(update_trans.c:1075:top_trans_stop()) exa5-MDT0003-osp-MDT0007: write updates failed: rc = -2

And the operation mv failed, which caused the renamed directory not accessible.
