To whom it may concern,
I have a disk for which smartctl fails with the following assertion, asking me to contact smartmontools-support at listi.jpberlin.de <mailto:smartmontools-support at listi.jpberlin.de>:
Smartctl: Exception: json.cpp(39): Assertion failed: 'a' <= c && c <= 'z'
Please inform smartmontools-support at listi.jpberlin.de, including output of smartctl -V.
As requested, I am enclosing the output of "smartctl -V“. The system is running AlmaLinux 8. The affected disk is a Seagate ST24000NM007H datacenter SAS disk with 24 TB. ZFS is reporting 21 read errors on the disk which is why I was trying to query its SMART values. The command leading to the error was "smartctl -aA /dev/disk/by-id/scsi-SSEAGATE_ST24000NM007H_ZYD07LL3“ (but same happens with „-x“ instead of „-aA“). I am also enclosing the full output of the failing smartctl run.
The command does work for all other disks in the system, 11 of which being the same model.
Please let me know if I can provide further information.
Kind regards,
Christian
