Subject: Input/output error, nothing appended in dmesg
Date: Fri, 05 Aug 2016 20:42:12 +0900 [thread overview]
Message-ID: <ff95214f4e2dd819d42dee7dff5f6580@admin.virtall.com> (raw)
I'm getting occasional (every few weeks) input/output errors on a btrfs
filesystem with compress-force=zlib, running on Amazon EC2, with 4.5.2
kernel:
# cat 2016-08-02/serverX/syslog.log
cat: 2016-08-02/serverX/syslog.log: Input/output error
Strangely, nothing gets appended in dmesg:
# dmesg -c
#
The filesystem stores mostly remote syslog files (so, all text files,
appended to).
Expected?
# btrfs fi show /var/log/remote/
Label: none uuid: 5cec93a8-7894-41f6-94a4-9d9b58216dd4
Total devices 1 FS bytes used 146.55GiB
devid 1 size 200.00GiB used 153.01GiB path /dev/xvdb
# btrfs fi df /var/log/remote/
Data, single: total=149.00GiB, used=144.50GiB

Metadata, single: total=4.01GiB, used=2.05GiB
