From d5976e2ca90f16074216a32e267e2652acd32bd9 Mon Sep 17 00:00:00 2001 From: Ashish Pandey Date: Wed, 27 Jul 2016 15:49:25 +0530 Subject: posix: Do not move and recreate .glusterfs/unlink directory Problem: At the time of start of a volume, it is checked if .glusterfs/unlink exist or not. If it does, move it to landfill and recreate unlink directory. If a volume is mounted and we write data on it till we face ENOSPC, restart of that volume fails as it will not be able to create unlink dir. mkdir will fail with ENOSPC. This will not allow volume to restart. Solution: If .glusterfs/unlink directory exist, don't move it to landfill. Delete all the entries inside it. master - http://review.gluster.org/#/c/15030/ Change-Id: Icde3fb36012f2f01aeb119a2da042f761203c11f BUG: 1364365 Signed-off-by: Ashish Pandey Reviewed-on: http://review.gluster.org/15093 Smoke: Gluster Build System CentOS-regression: Gluster Build System NetBSD-regression: NetBSD Build System Reviewed-by: Pranith Kumar Karampuri --- tests/bugs/posix/bug-1360679.t | 36 ++++++++++++++++++++++++++++++++++++ 1 file changed, 36 insertions(+) create mode 100644 tests/bugs/posix/bug-1360679.t (limited to 'tests') diff --git a/tests/bugs/posix/bug-1360679.t b/tests/bugs/posix/bug-1360679.t new file mode 100644 index 00000000000..fbb9d027ddb --- /dev/null +++ b/tests/bugs/posix/bug-1360679.t @@ -0,0 +1,36 @@ +#!/bin/bash + +. $(dirname $0)/../../include.rc +. $(dirname $0)/../../volume.rc +. $(dirname $0)/../../fileio.rc + +cleanup +function num_entries { + ls -l $1 | wc -l +} + +function create_unlink_entry { + for i in {0..1} + do + mkdir -p $B0/${V0}$i/.glusterfs/unlink/{1..3}/{1..10}/1 + dd if=/dev/urandom of=$B0/${V0}$i/.glusterfs/unlink/file-1 bs=1M count=1 + dd if=/dev/urandom of=$B0/${V0}$i/.glusterfs/unlink/file-2 bs=1M count=1 + dd if=/dev/urandom of=$B0/${V0}$i/.glusterfs/unlink/1/file-1 bs=1M count=1 + dd if=/dev/urandom of=$B0/${V0}$i/.glusterfs/unlink/2/file-1 bs=1M count=1 + dd if=/dev/urandom of=$B0/${V0}$i/.glusterfs/unlink/3/file-1 bs=1M count=1 + ln $B0/${V0}$i/.glusterfs/unlink/file-1 $B0/${V0}$i/.glusterfs/unlink/file-link + ln -s $B0/${V0}$i/.glusterfs/unlink/1 $B0/${V0}$i/.glusterfs/unlink/link + ln -s $B0/${V0}$i/.glusterfs/unlink/2 $B0/${V0}$i/.glusterfs/unlink/link-2 + done +} + +TEST glusterd +TEST pidof glusterd +TEST $CLI volume create $V0 disperse 6 redundancy 2 $H0:$B0/${V0}{0..5} +TEST $CLI volume start $V0 +TEST $CLI volume stop $V0 +create_unlink_entry +TEST $CLI volume start $V0 +EXPECT_WITHIN $UNLINK_TIMEOUT "^1$" num_entries $B0/${V0}0/.glusterfs/unlink/ +EXPECT_WITHIN $UNLINK_TIMEOUT "^1$" num_entries $B0/${V0}1/.glusterfs/unlink/ +cleanup; -- cgit
