From e58b55ed9b2e802e6c3e908cbbad71c00f6c5b97 Mon Sep 17 00:00:00 2001 From: Kotresh HR Date: Tue, 9 Jun 2015 10:44:44 +0530 Subject: features/changelog: Do htime setxattr without XATTR_REPLACE flag HTIME_KEY marks the last changelog rolled over. The xattr is maintained on .glusterfs/changelog/htime/HTIME.TSTAMP file. On every rollover of the changelog file, the xattr is updated. It is being updated with XATTR_REPLACE flag as xattr gets created during changelog enable. But it is once found that the xattrs on the file is cleared and is not reproduced later on. This patch protects that case, if it happens by setting xattr without XATTR_REPLACE flag in failure case. The reason behind doing this in failure case is not to mask the actual cause of xattrs getting cleared. This provides the log message if the original issue still exists but the consequential effects are fixed. Also changed the log messages to depict the events happened during changelog enable.
