<div dir="ltr"><div class="gmail_quote"><div dir="ltr">Hello, I am trying this list as I wasn't able to get much assistance on another lace.</div><div dir="ltr"><br></div><div dir="ltr">We had a LVM made up of 4 disks and lost a drive. I pulled the drive and replaced it and then tried to repair but then when I tried to recover it, it turned out it was a striped volume. (Its not my server! Never thought they would put the data on a striped volume). <div><br></div><div>So I returned the original drive back into the same slot to see if there was a way to recover the data. </div><div><br></div><div>This is lvm2 2.02.95-8</div><div><div><br></div><div>The drive that failed was /dev/sdc. When I put in back in it magically started working. I want to see if its possible to try to recover the data because all the drives are actually still in the exact same slots. The main issue is it is not finding the logical volume anymore.</div><div><div><br></div><div>Any help appreciated.</div><div><br></div><div>AB</div><span class=""><font color="#888888"><div><br></div><div><br></div></font></span></div><div><br></div><div>Below are my logs. </div><div><br></div><div><div>/# pvscan -v</div><div> Wiping cache of LVM-capable devices</div><div> Wiping internal VG cache</div><div> Walking through all physical volumes</div><div> PV /dev/sdb VG data lvm2 [465.76 GiB / 465.76 GiB free]</div><div> PV /dev/sdd VG data lvm2 [465.76 GiB / 465.76 GiB free]</div><div> PV /dev/sde VG data lvm2 [465.76 GiB / 465.76 GiB free]</div><div> PV /dev/sdf VG data lvm2 [465.76 GiB / 465.76 GiB free]</div><div> PV /dev/sdc VG data lvm2 [465.76 GiB / 465.76 GiB free]</div><div> Total: 5 [2.27 TiB] / in use: 5 [2.27 TiB] / in no VG: 0 [0 ]</div></div><div><br></div><div><br></div><div><div>:/# vgscan -v</div><div> Wiping cache of LVM-capable devices</div><div> Wiping internal VG cache</div><div> Reading all physical volumes.
