From: Johannes Stezenbach Subject: 4.7.0-rc7 ext4 error in dx_probe Date: Mon, 18 Jul 2016 12:57:07 +0200 Message-ID: <20160718105707.GA4253@sig21.net> Mime-Version: 1.0 Content-Type: text/plain; charset=us-ascii Cc: tytso@mit.edu, linux-kernel@vger.kernel.org To: linux-ext4@vger.kernel.org Return-path: Content-Disposition: inline Sender: linux-kernel-owner@vger.kernel.org List-Id: linux-ext4.vger.kernel.org Hi, I'm running 4.7.0-rc7 with ext4 on lvm on dm-crypt on SSD and out of the blue on idle machine the following error message appeared: [373851.683131] EXT4-fs (dm-3): error count since last fsck: 1 [373851.683151] EXT4-fs (dm-3): initial error at time 1468438194: dx_probe:740: inode 22288562 [373851.683158] EXT4-fs (dm-3): last error at time 1468438194: dx_probe:740: inode 22288562 inode 22288562 is a directory with ~800 small files in it, but AFAICT nothing was accessing it, no cron job running etc. No further error message was logged. Accessing the directory and the files in it also gives no further errors. Searching back in the log at date -d @1468438194 I found: Jul 13 21:29:54 foo kernel: EXT4-fs error (device dm-3): dx_probe:740: inode #22288562: comm git: Directory index failed checksum Time to run fsck? Is it the consequence of a previous crash (I had many recently)? Johannes
