RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Description Martin Pitt 2018-07-05 12:42:47 UTC 
Description of problem: In current RHEL 7.6 nightlies, udisks2 or the underlying libblockdev has a regression: Formatting fails with

    Error wiping device: The function 'bd_fs_wipe' called, but not implemented!


Version-Release number of selected component (if applicable):

# rpm -qa|egrep 'udisks|blockdev'
udisks2-2.7.3-7.el7.x86_64
udisks2-iscsi-2.7.3-7.el7.x86_64

libblockdev-lvm-2.18-2.el7.x86_64
libblockdev-fs-2.18-2.el7.x86_64


How reproducible: Always


Steps to Reproduce:
1. modprobe scsi_debug   # or take any other available block device
2. busctl call org.freedesktop.UDisks2 /org/freedesktop/UDisks2/block_devices/sdb org.freedesktop.UDisks2.Block Format 'sa{sv}' ext4 0

Make *triple* sure here that "sdb" is really the one from scsi_debug, don't destroy your hard disk :)

Actual results: Fails with said error.

Expected results: Works (like in RHEL 7.5 or Fedora)

Additional info: Spotted by Cockpit integration tests in https://github.com/cockpit-project/cockpit/pull/9580
Comment 2 Martin Pitt 2018-07-05 15:51:31 UTC 
This also affects Mount() and Unmount():

# modprobe scsi_debug
# mkfs -t ext4 /dev/sdb
# udisksctl mount -b /dev/sdb
Error mounting /dev/sdb: GDBus.Error:org.freedesktop.UDisks2.Error.Failed: Error mounting /dev/sdb at /run/media/root/c095c9ac-9abf-4b45-ad98-8a8aa4c94aa0: The function 'bd_fs_mount' called, but not implemented!

# mount /dev/sdb /mnt
# udisksctl unmount -b /dev/sdb
Error unmounting /dev/sdb: GDBus.Error:org.freedesktop.UDisks2.Error.Failed: Error unmounting /dev/sdb: The function 'bd_fs_unmount' called, but not implemented!

libblockdev-fs looks quite reasonable, just like on Fedora 28 (except the latter has debug symbol links):

# rpm -ql libblockdev-fs | xargs ls -ld
lrwxrwxrwx. 1 root root    17 Jul  5 09:11 /usr/lib64/libbd_fs.so.2 -> libbd_fs.so.2.0.0
-rwxr-xr-x. 1 root root 58928 Jun 22 05:34 /usr/lib64/libbd_fs.so.2.0.0

# nm -D /usr/lib64/libbd_fs.so.2.0.0|grep bd_fs_mount
0000000000007dc0 T bd_fs_mount

So it seeems pretty well all udisks Filesystem operations are completely broken.

Comment 4 Martin Pitt 2018-07-09 13:56:37 UTC 
@Tomáš: Not sure if that was directed at me, but in RHEL 7 NTFS is generally not supported. We blacklist these tests in Cockpit for 7.5 as well (and of course 7.6). But of course it should still work for the other file systems.
Comment 5 Tomáš Bžatek 2018-07-09 14:11:55 UTC 
Caused by unavailable ntfs tools whose search for was added to libblockdev' fs plugin in v2.14 (rebased in RHEL7.6: bug 1545623).

Need to backport https://github.com/storaged-project/udisks/commit/e31199054797ca8de62d9d1f32a46a58f2211159
Comment 11 xhe@redhat.com 2018-08-09 01:24:56 UTC 
On the latest version of libudisks2-2.7.3-8.el7, it works well. I move to VERIFIED.
