Hi everyone in this community. I have installed a working two node cluster using the new RHEL5 clustersuite and RHEL5 x64. kernel: ...... 2.6.18-8.el5 cman: cman-2.0.64-1.0.1.el5 lvm2-cluster version: lvm2-cluster-2.02.16-3.el5 iscsi: iscsi-initiator-utils-6.2.0.742-0.6.el5 multipath: device-mapper-multipath-0.4.7-8.el5 What i am trying to do now is to connect my shared storage (iscsi) via lvm2 clustered VG and mirrored LV. I can successful create the PVs and VG.... but when activating the LV i get following errors in /var/log/messages: kernel: device-mapper: table: 253:6: mirror: Error creating mirror dirty log kernel: device-mapper: ioctl: error adding target to table dmeventd[4626]: dmeventd ready for processing. dmeventd[4626]: Monitoring mirror device, VG_mail-LV_mail for events lvm[4590]: Error locking on node mail1: device-mapper: reload ioctl failed: Invalid argument lvm[4590]: Error locking on node mail1: device-mapper: reload ioctl failed: Invalid argument lvm[4590]: Failed to activate new LV. What does this mean? Where to search for the mistake? Tried already to change locking mode in /etc/lvm/lvm.conf to 2 and use locking_library liblvm2clusterlock.so from x32 RHEL4.5 without success also. (i know x32 and x64 os, but i thought it's worth a try..... couldn't find an external locking lib for RHEL5 x64) Just for info, please find below my system config: lvm.conf: library_dir = "/usr/lib64" locking_type = 3 fallback_to_clustered_locking = 1 fallback_to_local_locking = 1 locking_dir = "/var/lock/lvm" mirror_log_fault_policy = "allocate" mirror_device_fault_policy = "remove" iscsi devices: 2 infortrend iscsi storage boxes with each raid 6 + Hotspare LV size should be 6 TeraByte -> mirrored to 2nd box multipath -l shows: (right now there is only one path configured) mail_m0 (3600d0230006fb0c300065568b855f301) dm-2 IFT,A16E-G2130-4 [size=5.9T][features=0][hwhandler=0] \_ round-robin 0 [prio=0][active] \_ 3:0:0:0 sde 8:64 [active][undef] mail_mlog (3600d0230006fb0c300065568b855f300) dm-3 IFT,A16E-G2130-4 [size=200M][features=0][hwhandler=0] \_ round-robin 0 [prio=0][active] \_ 3:0:0:1 sdf 8:80 [active][undef] mail_m1 (3600d0230006fbccc0006624409e63600) dm-4 IFT,A16E-G2130-4 [size=5.9T][features=0][hwhandler=0] \_ round-robin 0 [prio=0][active] \_ 4:0:0:0 sdb 8:16 [active][undef] vgdisplay shows: --- Volume group --- VG Name VG_mail System ID Format lvm2 Metadata Areas 3 Metadata Sequence No 7 VG Access read/write VG Status resizable Clustered yes Shared no MAX LV 0 Cur LV 4 Open LV 0 Max PV 0 Cur PV 3 Act PV 3 VG Size 11.82 TB PE Size 128.00 MB Total PE 96824 Alloc PE / Size 96667 / 11.80 TB Free PE / Size 157 / 19.62 GB VG UUID cdjlgF-n0dh-mlDo-wPco-RvFl-C3fO-PUQSuh PV Size 128MB for getting 6 TB volume. command issued to create LV: lvcreate -m1 -L 5.90T -n LV_mail VG_mail /dev/mapper/mail_m0 /dev/mapper/mail_m1 /dev/mapper/mail_mlog lvs shows: LV VG Attr LSize Origin Snap% Move Log Copy% LV_mail VG_mail mwi-d- 5.90T LV_mail_mlog 0.00 LogVol00 VolGroup00 -wi-ao 3.41G LogVol01 VolGroup00 -wi-ao 480.00M but LV is NOT active because i get the error mentioned above! Any ideas? Every hint would be highly appriaciated. Thanks Thomas |
