Convert test to use only ext4 instead of 300M demanding XFS.
Shorten 'B' files to 4K and use 4K strip size with >raid1 arrays
so we do not risk spreading of the file across stripe.
Also use easier 'aux corrupt_dev()' method to introduce a bit
corruption into a block device with integrity.
TODO: shorten _wait_recalc (should't be needed).
Convert test to use a single skeleton and only different pieces
keep in separate tests.
Lower raid disk usage to smaller size and switch to ext4
as way less demanding fileystem.
Different sequences of steps that could be used to handle raid LVs
after VG takeover (what would happen in cluster failover) combined
with the loss of a disk.
Replace spaces with \040 in directory paths from getmntent (mtab).
The recent commit 5374a44c57 compares mount point directory paths
from /etc/mtab and /proc/mounts, in order to detect when a mounted
LV has been renamed. The directory path comparison does not work
correctly when the path contains spaces because getmntent uses
ascii space chars and proc replaces spaces with \040.
Fix hang of vgimportclone command when:
the PV(s) being imported are not actually clones/duplicates, and
the -n vgname arg is the same as the current vgname.
(Not the intended use of the command, but it should still work.)
In this case, the old and new vgnames ended up being the same, when
the code expected they would be different. A file lock on both the
old and new vgnames is used, so when both flocks are on the same
file, the second blocks indefinitely.
Fix the new vgname to be the old name plus a numeric suffix, which
is the expected result.
There were a couple of cases where lvresize, without --fs resize,
was resizing the crypt layer above the LV. Resizing the crypt
layer should only be done when fs resizing is enabled (even if the
fs is already small enough due to being independently reduced.)
Also, check the size of the crypt device to see if it's already
been reduced independently, and skip the cryptsetup resize if
it's not needed.
The recent change that verifies sys_serial system.devices entries
using the PVID did not exclude non-PV devices from being checked.
The verification code would attempt to use du->pvid which was null
for the non-PVs causing a segfault.
Since now we change deduplication with V4 table line change,
the modification tends to be faster and we can capture for a few ms
also 'status' about opening or closing deduplication index.
Use 'grep -E' to handle both words.
Handle multiple devices using the same serial number as
their device id. After matching devices to devices file
entries, if there is a discrepency between the ondisk PVID
and the devices file PVID, then rematch devices to
devices file entries using PVID, looking at all disks
on the system with the same serial number.
These files are automatically cleared on reboot given
that /run is tmpfs, and that remains the primary way
of clearing online files.
But, if there's extreme use of vgcreate+pvscan+vgremove
between reboots, then removing online files in vgremove
will limit the number of unused online files using space
in /run.
The new option "--fs String" for lvresize/lvreduce/lvextend
controls the handling of file systems before/after resizing
the LV. --resizefs is the same as --fs resize.
The new option "--fsmode String" can be used to control
mounting and unmounting of the fs during resizing.
Possible --fs values:
checksize
Only applies to reducing size; does nothing for extend.
Check the fs size and reduce the LV if the fs is not using
the affected space, i.e. the fs does not need to be shrunk.
Fail the command without reducing the fs or LV if the fs is
using the affected space.
resize
Resize the fs using the fs-specific resize command.
This may include mounting, unmounting, or running fsck.
See --fsmode to control mounting behavior, and --nofsck to
disable fsck.
resize_fsadm
Use the old method of calling fsadm to handle the fs
(deprecated.) Warning: this option does not prevent lvreduce
from destroying file systems that are unmounted (or mounted
if prompts are skipped.)
ignore
Resize the LV without checking for or handling a file system.
Warning: using ignore when reducing the LV size may destroy the
file system.
Possible --fsmode values:
manage
Mount or unmount the fs as needed to resize the fs,
and attempt to restore the original mount state at the end.
nochange
Do not mount or unmount the fs. If mounting or unmounting
is required to resize the fs, then do not resize the fs or
the LV and fail the command.
offline
Unmount the fs if it is mounted, and resize the fs while it
is unmounted. If mounting is required to resize the fs,
then do not resize the fs or the LV and fail the command.
Notes on lvreduce:
When no --fs or --resizefs option is specified:
. lvextend default behavior is fs ignore.
. lvreduce default behavior is fs checksize
(includes activating the LV.)
With the exception of --fs resize_fsadm|ignore, lvreduce requires
the recent libblkid fields FSLASTBLOCK and FSBLOCKSIZE.
FSLASTBLOCK*FSBLOCKSIZE is the last byte used by the fs on the LV,
which determines if reducing the fs is necessary.
