-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hello all, we are currently facing some handling issues using mirrored LVM-lvols in a cluster: We have two diffent storage systems which should be mirrored using host-based mirroring. AFAIK cmirrored lvols are the only supported mirroring solution under RHEL56. So we have three multipath devices which are used for 2 data and one log-volume. We added these three pvs to one volumegroup and created the logical volume using the following command: lvcreate -m1 -L 10G -n lv_mirrored /dev/mpath/mpath0p1 /dev/mpath2p1 /dev/mpath/mpath1p1 The volume replicates ok and everything is fine.... until we remove one storage-side of the mirror. Then LVM simply removes the missing pv and the mirror is simply removed - which I think is ok; if it will be recreated after readding the failed mirror-side. Unfortunately LVM doesn't do anything such - is there a special configuration-option which we missed? And keep in mind: there might be a huge amount of lvms which have to be re-mirrored. So manual interaction shouldn't be the default option ;) Regards, Andreas -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.14 (GNU/Linux) Comment: Using GnuPG with Red Hat - http://enigmail.mozdev.org/ iQIcBAEBAgAGBQJN1lXCAAoJEK45y/Z6LXho/4wP/AjjoOGX3pRoe3XRARumkTKW C/+8Jjm4+aC4VP1ycVkHZhrdGlzy4QmTtCFTCv40AgPU2YT/Aq+PqfNnn4SNqpwR c815zd9Gk+uQwwR55kloX232eZzFEw2wVa9PWxOmKwaeuYSEOz8GmLVZrPVc3V9p MNr6wkV5gzTzhC2v75KOZ4PchOiuYEDbhCd5GFDKmpyTeHTq/uNW2yRnjInAX8L9 8UCJ1JEzo4ry2mIBK1J+du5YtKx4uDLB893rgbf+T5Cci3hsLJ9/gfF1VU80b+o/ uVc5t31rwUwMaFSyt9wtEhMQB0ggbyiQqzzjSP5wnnakd6lbJKhB06wM5XqGuUkS ZetkZdH+etALFpt3PrV7F4+LDwGnP7Hw438czKjD+Xk21fd7idSo3vhtWjArPgKp L+b5fxB8JoUGN7x2S3239aDMI6BmxTTZ+QnsamYzSy0IdHYghPSjPSsx8H5laJWd I03F2sfPWwB8vWVweHvNbxfFjZfmEaawoMqGanoGktj/RYgvUpPZJD+YHDVGXohN VoRVmB+t4JVSWb15BzOhzkAI//LtXjSHmtcnBuYQf8G0Q2v/r0x/hv04F9/0fQ0l dPlU1vh244fh0nG5BMCJlKPcdcpGJnGy4kIKOknOi+NuI2ZxxvSLIY5WbrqAwkBX QXYt6plJ5DgzWCa8fNYN =0I6Z -----END PGP SIGNATURE----- -- Linux-cluster mailing list Linux-cluster@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/linux-cluster
