[linux-lvm] damaged disk in a logical volume



Hi,

I was working with a logical volume which was built with four disks. The fourth
one has been damaged (I don't know the cause), even mkfs fails, probably some
damaged sector. I would like to know if it's possible to recover some data from
the other disks. I tried to remove the damaged disk from the logical volume but
I can't deal with any physical volume if one of them are bad.

My file.vg:

maltes01 {
        id = "iHkB9I-og1A-TrIV-ZefG-Ai0W-5rk5-52kR1t"
        seqno = 0
        status = ["RESIZEABLE", "READ", "WRITE"]
        extent_size = 8192              # 4 Megabytes
        max_lv = 255
        max_pv = 255

        physical_volumes {

                pv0 {
                        id = "TPWYqO-TXGt-CIjl-fQQN-rMnZ-tpjQ-GuhJc3"
                        device = "/dev/sda"     # Hint only

                        status = ["ALLOCATABLE"]
                        pe_start = 384
                        pe_count = 17501        # 68.3633 Gigabytes
                }

                pv1 {
                        id = "5eFxOP-YwQI-ns89-YW51-YNnY-xmmB-HIBwWJ"
                        device = "/dev/sdb"     # Hint only

                        status = ["ALLOCATABLE"]
                        pe_start = 384
                        pe_count = 17537        # 68.5039 Gigabytes
                }

                pv2 {
                        id = "UvlyW9-hY4u-50Zp-plNV-1Fco-R0hr-vgbIiM"
                        device = "/dev/sdc"     # Hint only

                        status = ["ALLOCATABLE"]
                        pe_start = 384
                        pe_count = 17537        # 68.5039 Gigabytes
                }

                pv3 {
                        id = "BSWMyc-bEfD-vfTJ-px8U-G8nt-M8J6-QHvHnz"
                        device = "/dev/sdd"     # Hint only

                        status = ["ALLOCATABLE"]
                        pe_start = 384
                        pe_count = 4379 # 17.1055 Gigabytes
                }
        }

}

Any idea? Thanks in advance
