Gracias a todos,
El servidor esta en remoto y ahora mismo no puedo ir fisicamente a
pincha otro disco, pero tengo un disco de 2TB por USB conectado con
espacio suficiente.
He ejecutado esto dentro de una consola virtual (screen):
# ddrescue -f -n -v /dev/sdb1 /mnt/2TBUSB/sdb1.img /root/recovery.log
GNU ddrescue 1.21
About to copy 1000 GBytes from /dev/sdb1 to /mnt/2TBUSB/sdb1.img.
Starting positions: infile = 0 B, outfile = 0 B
Copy block size: 128 sectors Initial skip size: 128 sectors
Sector size: 512 Bytes
Press Ctrl-C to interrupt
ipos: 1149 MB, non-trimmed: 0 B, current rate: 27656 kB/s
opos: 1149 MB, non-scraped: 0 B, average rate: 39622 kB/s
non-tried: 999054 MB, errsize: 0 B, run time: 29s
rescued: 1149 MB, errors: 0, remaining time: 7h
percent rescued: 0.11% time since last successful read: 0s
Copying non-tried blocks... Pass 1 (forwards)
Me he guiado de esta guia:
https://datarecovery.com/rd/how-to-clone-hard-disks-with-ddrescue/
Si me da algun fallo tendre que añadir mas parametros como "-r3". Ojala no.
Quedan 7 horas a que termine, así que toca esperar.
Gracias de nuevo, os mantengo informado.
Un saludo.
