I suppose the controller / drive are implicated in some way. if labelclear doesnt work, you need to use dd if/dev/zero to zero out the first x amount 100mb-1g whatever, and then the end of the disk as well then reboot. Other systems are all older and not using SATA drives. Youll probably need to erase the end of the disk as well. Only one system, a Lenovo Thinkpad 520i, exhibits this problem. I am running four Debian testing systems partitioned and configured almost identically, software-wise. systemd: /lib/systemd/system-generators/systemd-gpt-auto-generator failed with error code 1. blkid reports disk as zfsmember if it has a zfsmember partition 918 Closed sschmitz opened this issue on 9 comments sschmitz commented on edited Create several partitions on a disk. If you want it to be an empty partition without any filesystem (or data) on it, then you just zero it out with shred or dd. systemd-gpt-auto-generator: /dev/sda: failed to determine partition table type: Input/output error Just tested with mkfs.ext4 -L test /dev/sda3 and then e2label /dev/sda3 '' on a spare empty partition. Every time system is booted lines such as the following appear on-screen and in dmesg: Minor bug with no obvious (to me) consequences. Reported from previous version of systemd in was suggested that - since bug is still reproducible - I report this upstream. wipefs would delete the ZFS signature and mount using UUID would work. The extra signature is still there and mount using UUID still fails. Zero out the first 72MB of the device # dd if=/dev/zero of=/dev/vx/rdmp/c1t1d0s2 bs=1024 count=72000Ģ.Running Debian testing (fully updated) using standard repository's systemd version 228-4+b1. Attempting to fix the problem by deleting the ZFS I used the wipefs to list the label and use it to delete it ineffective) wipefs writes that it deletes it, but does not seem to do anything. Since wipefs does not erase the filesystem itself nor any other data from the device you will need to do this. Same can be achieved using the type option or in short -t. In cases where the ZFS label is not at the expected offset a more general wipe operation will be required to ensure that the ZFS label is removed and the disk can be initialized.īefore proceeding, review and ensure the disk is not in use in any other capacity - the following procedure will irrecoverably destroy the VTOC and any data in the beginning of the disk.ġ. To remove only a specific signature you could use the offset option or in short -o. or the ZFS intent log, and what this does is it allows RAM and SSDs to work as a cache. If running the recommended DD command correct the condition and the disk remains unable to initialize then the ZFS label is not at the expected offset. One highlight that ZFS has over traditional RAID is that its not. Usage: Assuming the drive in question is /dev/sdd. # dd if=/dev/zero of=/dev/vx/rdmp/c1t1d0s2 oseek=31 bs=512 count=1 I have used the program wipefs from the Debian/Ubuntu package util-linux to wipe not only ZFS used drives no longer in a zpool but any drive I want to reuse so I know the past formatting is gone. The above indicates that VM is detecting a ZFS signature on slice 2: I opened the disk with fdisk /dev/sdc and there was a red warning saying something like that: 'The type of disk is set to zfsmember. I went away for the summer to go work in another province. > I did not know at the time that ZFS on top of hardware raid is a bad thing to do. It was pretty straightforward because the raid card showed the raid array as a big, 7.8 tb disk. If you still want to initialize this device for VxVM use, please destroy the zpool by running 'zpool' command if it is still active, and then remove the ZFS signature from each of these slice(s) as follows:ĭd if=/dev/zero of=/dev/vx/rdmp/c1t1d0s oseek=31 bs=512 count=1 FreeNas's preferred filesystem is ZFS, so I formatted the raid disk as ZFS. Slice(s) 2 are in use as ZFS zpool (or former) devices. VxVM vxdisksetup ERROR V-5-2-5716 Disk c1t1d0s2 is in use by ZFS. Error Message # /etc/vx/bin/vxdisksetup -ir c1t1d0 It will be erased on (w)rite' and I pressed 'w' to write the changes () (there were no changes) and whole disk is wiped out That was not an issue at this particular case, as I was poking around. If one disk in a mirrored or RAID-Z device is removed. I opened the disk with fdisk /dev/sdc and there was a red warning saying something like that: 'The type of disk is set to zfsmember. Depending on the data replication level of the pool, this removal might or might not result in the entire pool becoming unavailable. Storage Foundation 5.1 will not initialize disks on which a ZFS label is detected but the detection is not limited to block 31 so if a ZFS label resides somewhere else in the first 32 blocks of a partition, the error will be reported but zeroing out offset 31 will not fix the issue. If a device is completely removed from the system, ZFS detects that the device cannot be opened and places it in the REMOVED state.
