From 27e1d105fb805327993f468aeccef60ab2743854 Mon Sep 17 00:00:00 2001 From: Giulio Fidente Date: Thu, 29 Sep 2016 13:52:32 +0200 Subject: Set ceph osd max object name and namespace len on upgrade when on ext4 As per [1] we need to lower osd max object name and namespace len when upgrading from Hammer and the OSD is backed by ext4. These could also be given via ExtraConfig but on upgrade we only run puppet apply after this script is executed, so the values won't be effective unless the daemon is restarted. Yet we do not want puppet to restart the daemon because we can't bring all OSDs down unconditionally or guests will die. 1. http://tracker.ceph.com/issues/16187 Co-Authored-By: Michele Baldessari Co-Authored-By: Dimitri Savineau Change-Id: I7fec4e2426bdacd5f364adbebd42ab23dcfa523a Closes-Bug: 1628874 --- extraconfig/tasks/major_upgrade_ceph_storage.sh | 10 ++++++++++ 1 file changed, 10 insertions(+) (limited to 'extraconfig') diff --git a/extraconfig/tasks/major_upgrade_ceph_storage.sh b/extraconfig/tasks/major_upgrade_ceph_storage.sh index 705e84eb..56b54e22 100644 --- a/extraconfig/tasks/major_upgrade_ceph_storage.sh +++ b/extraconfig/tasks/major_upgrade_ceph_storage.sh @@ -69,6 +69,16 @@ elif [[ "$UPDATED_VERSION" =~ ^10\.2.* ]]; then # Replay udev events with newer rules udevadm trigger && udevadm settle + # If on ext4, we need to enforce lower values for name and namespace len + # or ceph-osd will refuse to start, see: http://tracker.ceph.com/issues/16187 + for OSD_ID in $OSD_IDS; do + OSD_FS=$(findmnt -n -o FSTYPE -T /var/lib/ceph/osd/ceph-${OSD_ID}) + if [ ${OSD_FS} = ext4 ]; then + crudini --set /etc/ceph/ceph.conf global osd_max_object_name_len 256 + crudini --set /etc/ceph/ceph.conf global osd_max_object_namespace_len 64 + fi + done + # Enable systemd unit systemctl enable ceph-osd.target for OSD_ID in $OSD_IDS; do -- cgit 1.2.3-korg
