While testing with tehj default 3000 MB RAM in the minikube VM, creating
a encrypted RBD volume fails because 'cryptsetup' gets killed:
[ 766.072585] Out of memory: Kill process 18497 (cryptsetup) score 1182 or sacrifice child
[ 766.072589] Killed process 18497 (cryptsetup) total-vm:863136kB, anon-rss:510336kB, file-rss:10788kB, shmem-rss:0kB
[ 766.072688] oom_reaper: reaped process 18497 (cryptsetup), now anon-rss:510336kB, file-rss:10780kB, shmem-rss:0kB
Using 4 GB RAM should prevent this from occuring.

In case kubectl did not get installed (VM_DRIVER != none),
scripts/minikube.sh can fail when kubectl is not in the path. By running
the "kubectl cluster-info" command through minikube, the script will
succeed.

In case there is a minikube executable in the $PATH already, use that
for all commands. If there is none, install_minikube() will place a
newly downloaded executable in /usr/local/bin which will be used by the
full pathname, so that commands as root without /usr/local/bin in the
$PATH will work.

The command fails when PWD=/. It is unclear what the command tries to

When starting minikube as root with --driver=kvm2, minikube complains
that this is not the right thing to do. However, in the CentOS CI we
really want to run as root, as that makes the scripts simpler.
Add the --force option while starting, so that minikube does not abort
anymore.

The jjb-validate job can not be run in parallel, so it may fail when
multiple PRs for the ci/centos branch are sent. However, the ci/centos
branch is not very active, so problems should be minimal.
In case of problems, leave the following comment in the PR and the job
should restart:
/retest ci/centos/jjb-validate

Most consumers of util.ExecCommand() need to convert the returned []byte
format of stdout and/or stderr to string. By having util.ExecCommand()
return strings instead, the code gets a little simpler.
A few commands return JSON that needs to be parsed. These commands will
be replaced by go-ceph implementations later on. For now, convert the
strings back to []byte when needed.
Signed-off-by: Niels de Vos <ndevos@redhat.com>
All calls to util.ExecCommand() now pass the context.Context. In some
cases this is not possible or needed, and util.ExecCommand() will not
log the command.
This should make debugging easier when command executions fail.

Current versions of the mkfs.xfs binary enable reflink support by
default. This causes problems on systems where the kernel does not
support this feature. When the kernel the feature does not support, but
the filesystem has it enabled, the following error is logged in `dmesg`:
XFS: Superblock has unknown read-only compatible features (0x4) enabled
Introduce a check to see if mkfs.xfs supports the `-m reflink=` option.
In case it does, pass `-m reflink=0` while creating the filesystem.
The check is executed once during the first XFS filesystem creation. The
result of the check is cached until the nodeserver restarts.

The sentinel error code had additional fields in the errors, that are
used nowhere. This leads to unneccesarily complicated code. This
change replaces the sentinel errors in utils with standard errors
created with errors.New() and adds a simple JoinErrors() function to
be able to combine sentinel errors from different code tiers.

In rbd E2E testing,we need to create snap and clone
as parallel operation.
This helps us to insure that functionality works when
we have parallel delete and create operations and also
it helps to catch bugs when we get parallel requests.

As we are adding new functionalities like Create/Delete
snapshot,Clone from Snapshot and Clone from Volume.
with the current implementation, there are only serial
operations allowed for this functionalities, for some
function we can allow parallel operations like
Clone from snapshot and Clone from Volume and Create
`N` snapshots on a single volume.
Delete Volume: Need to ensure that there is no clone,
Snapshot create and Expand volume in progress.
Expand Volume: Need to ensure that there is no clone,

In some ceph version if the subvolume is not present, the
ceph returns doesnot exists and in some version not found
error message. This commit fixes issue for both error
checks.
By only checking Error ENOENT: for doesnot exist seems good.
even if some error message changes in ceph ceph-csi wont get
any issue.
