Various other bus in clone sst script

[shinguz]

We got this error:

/usr//bin/wsrep_sst_clone: Zeile 118: [: 27-26: Ganzzahliger Ausdruck erwartet.
/usr//bin/wsrep_sst_clone: Zeile 120: [: 27-26: Ganzzahliger Ausdruck erwartet.

It is comparing those 2 numbers:

WSREP_SST: [ERROR] this operation requires MySQL client version 8.0.19, this client is '8.0.27-26.9' (20220321 17:35:22.017)

This is the problematic line in the code:

CLIENT_VERSION=$($MYSQL_CLIENT --version | grep -vi MariaDB | cut -d ' ' -f 4)
check_client_version $CLIENT_VERSION

This would solve the issue:

CLIENT_VERSION=$($MYSQL_CLIENT --version | grep -vi MariaDB | cut -d ' ' -f 4 | cut -b1-6)

Got another error:

Granted this:

grant select, update, delete, insert on performance_schema.* to sst@localhost;

But did not help. Documentation was not indicating anything:

Maybe this helps others to continue...
