| |
| | |
| * Heute Abend waren die Shares plötzlich unendlich langsam
| |
| * Teilweise waren sogar die Shares "offline"
| |
| * Im Serverraum dann folgendes Bild: eine LED einer Platte war dauerhaft an, also wie unter Dauerfeuer
| |
| * Das HDD LED des Boards war auch auf Dauerbetrieb ohne Flackern, also irgendwas schlimm im argen
| |
| * Ich habe die "schuldige" Platte einfach rausgezogen, danach wurde das Spare in den Verbund aufgenommen
| |
| * Es erfolgte der Weiterbetrieb störungsfrei und das Recovery mit Hilfe des Spares
| |
| * Ich habe gleich 2 neue 2 TB Platten bestellt
