VxRail: VxRail Manager-filbaseret sikkerhedskopiering fungerer ikke efter opgradering

Planlagt VxRail Manager-filbaseret sikkerhedskopiering konfigureres i VxRail Manager-kommandofanen:

vx_mgr:/var/log # cat /etc/cron.d/vxm_schedule_backup
0 0 * * * root /usr/bin/logger 'VxM rotation backup start.' && python /mystic/vxm_backup_restore/vxm_backup_restore.py -b

Der er ingen tilgængelige kompatible sikkerhedskopifiler, siden opgraderingen blev fuldført:

vx_mgr:/var/log # mcp_python /mystic/vxm_backup_restore/vxm_backup_restore.py -l

Logfilen "beskeder" viser den filbaserede sikkerhedskopiering startende på det planlagte tidspunkt:

2024-12-16T17:15:01.885958+00:00 vx_mgr CRON[19682]: (root) CMD (/usr/bin/logger 'VxM rotation backup start.' && python /mystic/vxm_backup_restore/vxm_backup_restore.py -b)

"/var/log/mystic/VxRailBackupRestore.log" fylder 0 og har været tom siden sidste opgradering:

vx_mgr:/home/mystic # ls -lh /var/log/mystic/VxRailBackupRestore.log
--w----r-T 1 root root 0 Dec 16 18:50 /var/log/mystic/VxRailBackupRestore.log

vx_mgr:/home/mystic # cat /var/log/mystic/VxRailBackupRestore.log

vx_mgr:/home/mystic #

På grund af interne Python-ændringer i VxRail Manager skal sikkerhedskopieringsscriptet køres med "mcp_python" i stedet for "python". Dette er for at indlæse de korrekte Python-miljøpakker i de nyere udgivelser.
Filbaserede sikkerhedskopieringer, der er planlagt i en VxRail-version før denne ændring, refererer stadig til "python" i operativsystemets crontab.

Når den gamle crontab-post startes, kører scriptet ikke korrekt:

vx_mgr:/var/log # python /mystic/vxm_backup_restore/vxm_backup_restore.py -b
Usage of the script: mcp_python /mystic/vxm_backup_restore/vxm_backup_restore.py

Dette påvirker opgraderinger på både 7.0 og 8.0 VxRail-versioner:

• Kodeopgraderinger fra før 7.0.520 til 7.0.520 eller højere.
• Kodeopgraderinger fra før 8.0.300 til 8.0.300 eller højere.
• Kodeopgraderinger fra før 7.0.520 til 8.0.300 eller højere.

Der er ingen fast kode tilgængelig, da dette undersøges yderligere.

Omkonfigurer den filbaserede sikkerhedskopiering af VxRail Manager som rodbruger ved hjælp af kommandoen: "mcp_python /mystic/vxm_backup_restore/vxm_backup_restore.py -c"
Eksempel:

vx_mgr:/var/log # mcp_python /mystic/vxm_backup_restore/vxm_backup_restore.py -c

Crontab-posten refererer nu til den korrekte kommando ved hjælp af "mcp_python":

vx_mgr:/var/log # cat /etc/cron.d/vxm_schedule_backup
0 0 * * * root /usr/bin/logger 'VxM rotation backup start.' && mcp_python /mystic/vxm_backup_restore/vxm_backup_restore.py -b
