Server / Výpadek webglobe.sk

« kdy: 31. 05. 2022, 11:54:32 »

Ahoj,

Mám tam pár slovenských klientů se servery a teď dostávám dost po čuni co se děje a sám nevím, máte někdo bližší info? Dík.

« kdy: 01. 03. 2021, 22:43:41 »

Zdravím jak virtualizovat efektivně a s co nejmenší chybovostí fyzicky server na, kterém je mdadm raid 1?

Virtuální server by měl být tradiční QEMU virtuál v proxmoxu.

Níže je detailní info:
