For example the LUN might be partitioned as LVM, then contain existing = filesystems etc... =20 - Would oVirt see that there is existing data on the LUN and simply = attach it as any other linux initiator (client) world, or would it try = to wipe the LUN clean and reinitialise it? Context: Investigating migration from XenServer to oVirt (4.2.0) All our iSCSI storage is currently attached to XenServer hosts, = XenServer formats those raw LUNs with LVM and VMs are stored within = them. If the answer to this is already out there and I should have found it by = searching, I apologise, please point me to the link and I'll RTFM. -- Sam McLeod https://smcleod.net https://twitter.com/s_mcleod --Apple-Mail=_0EC3C8C4-0EB1-4E35-A593-42CEA5D59791 Content-Transfer-Encoding: quoted-printable Content-Type: text/html; charset=us-ascii <html><head><meta http-equiv=3D"Content-Type" content=3D"text/html; = charset=3Dus-ascii"></head><body style=3D"word-wrap: break-word; = -webkit-nbsp-mode: space; line-break: after-white-space;" class=3D""><div = class=3D"">If one was to attach a shared iSCSI LUN as 'storage' to an = oVirt data centre that contains existing data - how does oVirt = behave?</div><div class=3D""><br class=3D""></div><div class=3D"">For = example the LUN might be partitioned as LVM, then contain existing = filesystems etc...</div><div class=3D""> </div><div class=3D"">- = Would oVirt see that there is existing data on the LUN and simply attach = it as any other linux initiator (client) world, or would it try to wipe = the LUN clean and reinitialise it?</div><div class=3D""><br = class=3D""></div><div class=3D""><br class=3D""></div><div = class=3D"">Context: Investigating migration from XenServer to oVirt = (4.2.0)</div><div class=3D""><br class=3D""></div><div class=3D"">All = our iSCSI storage is currently attached to XenServer hosts, XenServer = formats those raw LUNs with LVM and VMs are stored within = them.</div><div class=3D""><br class=3D""></div><div class=3D""><br = class=3D""></div><div class=3D""><br class=3D""></div><div class=3D""><i = class=3D"">If the answer to this is already out there and I should have = found it by searching, I apologise, please point me to the link and I'll = RTFM.</i></div><div class=3D""><div class=3D""> <div dir=3D"auto" style=3D"color: rgb(0, 0, 0); letter-spacing: normal; = text-align: start; text-indent: 0px; text-transform: none; white-space: = normal; word-spacing: 0px; -webkit-text-stroke-width: 0px; word-wrap: = break-word; -webkit-nbsp-mode: space; line-break: after-white-space;" = class=3D""><div dir=3D"auto" style=3D"color: rgb(0, 0, 0); = letter-spacing: normal; text-align: start; text-indent: 0px; = text-transform: none; white-space: normal; word-spacing: 0px; = -webkit-text-stroke-width: 0px; word-wrap: break-word; = -webkit-nbsp-mode: space; line-break: after-white-space;" class=3D""><div = dir=3D"auto" style=3D"word-wrap: break-word; -webkit-nbsp-mode: space; = line-break: after-white-space;" class=3D""><div style=3D"color: rgb(0, = 0, 0); font-family: Helvetica; font-size: 12px; font-style: normal; = font-variant-caps: normal; font-weight: normal; letter-spacing: normal; = text-align: start; text-indent: 0px; text-transform: none; white-space: = normal; word-spacing: 0px; -webkit-text-stroke-width: 0px;"><br = class=3D"">--<br class=3D"">Sam McLeod<br class=3D""><a = href=3D"https://smcleod.net" class=3D"">https://smcleod.net</a><br = class=3D"">https://twitter.com/s_mcleod</div></div></div></div> </div> <br class=3D""></div></body></html>= --Apple-Mail=_0EC3C8C4-0EB1-4E35-A593-42CEA5D59791--
