Subject: [lustre-devel] [PATCH 21/29] lnet: obi2lnd: don't try to reconnect if there's no listener
Date: Sun, 25 Apr 2021 16:08:28 -0400	[thread overview]
Message-ID: <1619381316-7719-22-git-send-email-jsimmons@infradead.org> (raw)
In-Reply-To: <1619381316-7719-1-git-send-email-jsimmons@infradead.org>

From: Li Dongyang <dongyangli@ddn.com>

For each discovery we try to reconnect up to retry_count times,
default to 5. during MDT mount process conf log, there will be
multiple discovery made for each OST.
If the OSTs are not up, the mount will have a long time out.

WC-bug-id: https://jira.whamcloud.com/browse/LU-14536
