Corrupt PV (wrong size)
by Richard Petty 05 Mar '12

05 Mar '12

GOAL: Retrieve a KVM virtual machine from an inaccessible LVM volume. DESCRIPTION: In November, I was working on a home server. The system boots to software mirrored drives but I have a hardware-based RAID5 array on it and I decided to create a logical volume and mount it at /var/lib/libvirt/images so that all my KVM virtual machine image files would reside on the hardware RAID. All that worked fine for a while. Later, I decided to expand that logical volume and that's when I made a mistake which wasn't discovered until about six weeks later when I accidentally rebooted the server. (Good problems usually require several mistakes.) Somehow, I accidentally mis-specified the second LMV physical volume that I added to the volume group. When trying to activate the LV filesystem, the device mapper now complains: LOG ENTRY: table: 253:3: sdc2 too small for target: start=2048, len=1048584192, dev_size=1048577586 As you can see, the length is greater than the device size. I do not know how this could have happened. I assumed that LVM tool sanity checking would have prevented this from happening but.... I tried to migrate the data from the corrupt PV1 to a newly added PV3 and then drop PV1. PV1 is not full and PV3 has enough space to be a migration destination. Unfortunately, is seems that using some of the LMV tools is predicated on the kernel being able to activate everything, which it refuses to do. Can't migrate the data, can't resize anything. I'm stuck. If course I've done a lot of Google research over the months but I have yet to see a problem such as this solved. Got ideas? Know an LVM guru? ========================== LMV REPORT FROM /etc/lvm/archive BEFORE THE CORRUPTION vg_raid { id = "JLeyHJ-saON-6NSF-4Hqc-1rTA-vOWE-CU5aDZ" seqno = 2 status = ["RESIZEABLE", "READ", "WRITE"] flags = [] extent_size = 8192 # 4 Megabytes max_lv = 0 max_pv = 0 metadata_copies = 0 physical_volumes { pv0 { id = "QaF9P6-Q9ch-bFTa-O3z2-3Idi-SdIw-YMLkQI" device = "/dev/sdc1" # Hint only status = ["ALLOCATABLE"] flags = [] dev_size = 419430400 # 200 Gigabytes pe_start = 2048 pe_count = 51199 # 199.996 Gigabytes } } logical_volumes { kvmfs { id = "Hs636n-PLcl-aivI-VbTe-CAls-Zul8-m2liRY" status = ["READ", "WRITE", "VISIBLE"] flags = [] segment_count = 1 segment1 { start_extent = 0 extent_count = 50944 # 199 Gigabytes type = "striped" stripe_count = 1 # linear stripes = [ "pv0", 0 ] } } } } ========================== LMV REPORT FROM /etc/lvm/archive AS SEEN TODAY vg_raid { id = "JLeyHJ-saON-6NSF-4Hqc-1rTA-vOWE-CU5aDZ" seqno = 13 status = ["RESIZEABLE", "READ", "WRITE"] flags = [] extent_size = 8192 # 4 Megabytes max_lv = 0 max_pv = 0 metadata_copies = 0 physical_volumes { pv0 { id = "QaF9P6-Q9ch-bFTa-O3z2-3Idi-SdIw-YMLkQI" device = "/dev/sdc1" # Hint only status = ["ALLOCATABLE"] flags = [] dev_size = 419430400 # 200 Gigabytes pe_start = 2048 pe_count = 51199 # 199.996 Gigabytes } pv1 { id = "8o0Igh-DKC8-gsof-FuZX-2Irn-qekz-0Y2mM9" device = "/dev/sdc2" # Hint only status = ["ALLOCATABLE"] flags = [] dev_size = 2507662218 # 1.16772 Terabytes pe_start = 2048 pe_count = 306110 # 1.16772 Terabytes } pv2 { id = "NuW7Bi-598r-cnLV-E1E8-Srjw-4oM4-77RJkU" device = "/dev/sdb5" # Hint only status = ["ALLOCATABLE"] flags = [] dev_size = 859573827 # 409.877 Gigabytes pe_start = 2048 pe_count = 104928 # 409.875 Gigabytes } pv3 { id = "eL40Za-g3aS-92Uc-E0fT-mHrP-5rO6-HT7pKK" device = "/dev/sdc3" # Hint only status = ["ALLOCATABLE"] flags = [] dev_size = 1459084632 # 695.746 Gigabytes pe_start = 2048 pe_count = 178110 # 695.742 Gigabytes } } logical_volumes { kvmfs { id = "Hs636n-PLcl-aivI-VbTe-CAls-Zul8-m2liRY" status = ["READ", "WRITE", "VISIBLE"] flags = [] segment_count = 2 segment1 { start_extent = 0 extent_count = 51199 # 199.996 Gigabytes type = "striped" stripe_count = 1 # linear stripes = [ "pv0", 0 ] } segment2 { start_extent = 51199 extent_count = 128001 # 500.004 Gigabytes type = "striped" stripe_count = 1 # linear stripes = [ "pv1", 0 ] } } } } ========================== I do have a intermediate versions of the /etc/lvm/archive files produced as I tinkered, in case they might be useful.

fedora vs. ubuntu minimal install
by Ranjan Maitra 05 Mar '12

05 Mar '12

Just wondering: why is the fedora minimal install iso (266 M) so much larger than the ubuntu one (26 M)? Clearly, these are two different distributions and I do not mean to imply that one is more preferable than the other in this aspect, so I was just wondering..... For the Fedora minimal install (I was referring to boot.iso) while for the Ubuntu, I was referring to mini.iso. I suspect that the answer may be that boot.iso can do far more than a minimal install, in which case (just speculation), wouldn't it be useful to also have a minimal install iso? I have not used Ubuntu much: that is my wife's distribution. I have stuck with Fedora from Day 1 even though it has become less stable since the middle of Fedora 14. (Just my observations: I still prefer F to U, though). Many thanks and best wishes, Ranjan

Cleaning /tmp
by Geoffrey Leach 05 Mar '12

05 Mar '12

Fedora (not just 16) leaves junk in /tmp. It's also using some of that junk, for example keyring-PRgjGV/. So what's the best way to reduce the clutter? Is there a service?
