3.6 : iSCSI LUN not detected
by Alexis HAUSER 11 Aug '16

11 Aug '16

Hi, I am reinstalling a new Node with a new hosted-engine and I would like to import an iSCSI storage from a previous ovirt installation. However, I can see all LUN present on that iSCSI but the one I want... I checked from the iSCSI array and this disk still exists, it's just not detected from Ovirt (3.6)... I tried to make a new data domain and chosed that same iSCSI and it's also not detected. Any ideas ? I didn't remove the storage from the Engine interface on the previous installation, just just turned off all VMs accessing the iSCSI and unplugged the cable. Is it possible there is still a lock file or something from the previous hypervisor ?

Convert OnApp VM to oVirt
by Fernando Frediani 11 Aug '16

11 Aug '16

Hi, Has anyone done a VM conversion from OnApp (therefore running in LVM) to oVirt/RHEV format being either buried in LVM or in a QCOW2 file. I've seen some instructions using qemu-img but wanted to find out if anyone has found any issues in this process. Any adjusts to be done before booting the VM the first time in the new platform ? Both hypervisors are KVM. Fernando

by David Gossage 10 Aug '16

Out of a 3 node cluster running oVirt 3.6.6.2-1.el7.centos with a 3 replicate gluster 3.7.14 starting a VM i just copied in on one node of the 3 gets the following errors. The other 2 the vm starts fine. All ovirt and gluster are centos 7 based. VM on start of the one node it tries to default to on its own accord immediately puts into paused for unknown reason. Telling it to start on different node starts ok. node with issue already has 5 VMs running fine on it same gluster storage plus the hosted engine on different volume. gluster nodes logs did not have any errors for volume nodes own gluster logs had this in log dfb8777a-7e8c-40ff-8faa-252beabba5f8 couldnt find in .glusterfs .shard or images/ 7919f4a0-125c-4b11-b5c9-fb50cc195c43 is the gfid of the bootable drive of the vm [2016-08-11 04:31:39.982952] W [MSGID: 114031] [client-rpc-fops.c:3050:client3_3_readv_cbk] 0-GLUSTER1-client-2: remote operation failed [No such file or directory] [2016-08-11 04:31:39.983683] W [MSGID: 114031] [client-rpc-fops.c:1572:client3_3_fstat_cbk] 0-GLUSTER1-client-2: remote operation failed [No such file or directory] [2016-08-11 04:31:39.984182] W [MSGID: 114031] [client-rpc-fops.c:1572:client3_3_fstat_cbk] 0-GLUSTER1-client-0: remote operation failed [No such file or directory] [2016-08-11 04:31:39.984221] W [MSGID: 114031] [client-rpc-fops.c:1572:client3_3_fstat_cbk] 0-GLUSTER1-client-1: remote operation failed [No such file or directory] [2016-08-11 04:31:39.985941] W [MSGID: 108008] [afr-read-txn.c:244:afr_read_txn] 0-GLUSTER1-replicate-0: Unreadable subvolume -1 found with event generation 3 for gfid dfb8777a-7e8c-40ff-8faa-252beabba5f8.

engine-backup and messages in web admin events pane
by Gianluca Cecchi 10 Aug '16

10 Aug '16

Hello, having oVirt Engine Version: 4.0.0.6-1.el7.centos, when I run on engine VM a command like # engine-backup --mode=backup --scope=all --file=/root/engine-backup.archive_$(date +%d-%m-%Y) --log=/root/engine-backup_$(date +%d-%m-%Y).log Backing up: Notifying engine - Files - Engine database 'engine' - DWH database 'ovirt_engine_history' Packing into file '/root/engine-backup.archive_09-08-2016' Notifying engine Done. I see then that in engine web admin events pane I only have rows of kind: Finished Started without any reference to what... See here: https://drive.google.com/file/d/0BwoPbcrMv8mvYXNLZkZtQ1FFRUU/view?usp=shari… Is it me running backup in the wrong way or was it improved in 4.0.1? Thanks, Gianluca

ovirt-ha-agent and too many open files error
by Gianluca Cecchi 10 Aug '16

10 Aug '16

Hello, I have a 4.0 test environment (single host with self hosted engine) where I have 6 VMs defined (5 running) and no much activity. I do't monitor this system very much. Now I have connected to it to evaluate upgrade to 4.0.1 and see that about 15 days ago the ovirt-ha-agent died because of too many open files....

It seems very strange to have reached this limit I presume the agent runs as vdsm user and that the oVirt installation creates the file /etc/security/limits.d/99-vdsm.conf with # This limits are intended for medium VDSM hosts, for large hosts scale these # numbers appropriately. # nproc should be the maximum amount of storage operations usage. # VMs run by "qemu" user, vm processes are not relavent to "vdsm" user limits. vdsm - nproc 4096 # nofile should be at least 3(stdin,stdour,stderr) * each external process. # 3 * 4096 = 12288 vdsm - nofile 12288 As a rough estimation (over estimation actually , due to many duplicates) I have now: # lsof -u vdsm | wc -l 488 Anything else to check?
