Mittwoch, April 15th, 2020Western Digital WD Red Type WD*EFAX with Shingled Magnetic Recording (SMR) – problems to add a new WD Red NAS drive to a RAID array although it was sold as a RAID disk
Mittwoch, April 15th, 2020
Shingled media recording (SMR) disk drives – take advantage of disk write tracks being wider than read tracks to partially overlap write tracks and so enable more tracks to be written to a disk platter. This means more data can be stored on a shingled disk than an ordinary drive. However SMR drives are not intended for random write IO use cases because the write performance is much slower than with a non-SMR drive. Therefore they are not recommended for NAS use cases featuring significant random write workloads

Mittwoch, April 15th, 2020Wireshark – how can I capture packets with CRC errors
Mittwoch, April 15th, 2020
Wireshark – can capture only the packets that the packet capture library can capture. Only the packets that the OS’s raw packet capture mechanism will allow it to capture. Unless the OS always supplies packets with errors such as invalid CRCs to the raw packet capture mechanism, or can be configured to do so, invalid CRCs to the raw packet capture mechanism Wireshark and other programs that capture raw packets such as tcpdump cannot capture those packets
