Re: [lustre-discuss] Best ways to backup a Lustre file system?

Re: [lustre-discuss] LNet supports IB HDR(200Gb) network?

OST configurations available today cannot endure such workloads. Yet when 200Gb throughput must be provided to OSS, there is an alternative such as dynamic load balancing on multi-rail configuration ( using 2 x 100Gb ports links for OSSes). regards, Jongwoo Han 2021년 10월 19일 (화) 오후 7:31, 홍재기 via

Re: [lustre-discuss] Failed to mount MDT

It seems your CONFIG directory in MDT is corrupt. I suggest that mount MDT as plain ext2fs ( # mount /dev/mapper/mpatha /mnt/tmp ) , backup CONFIG directory, and erase contents of CONFIG directory then mount as lustre filesystem. Regards, Jongwoo Han 2021년 10월 28일 (목) 오전 2:08, Рачко Антон

Re: [lustre-discuss] Is there aceiling of lustre filesystem a client can mount

I think your question is ambiguous. What ceiling do you mean? Total storage capacity? number of disks? number of clients? number of filesystems? Please be more clear about it. Regards, Jongwoo Han 2020년 7월 15일 (수) 오후 3:29, 肖正刚 님이 작성: > Hi, all > Is there a ceiling for a Lustre filesyste

Re: [lustre-discuss] Lnet Self Test

Have you tried MTU >= 9000 bytes (AKA jumbo frame) on the 25G ethernet and the switch? If it is set to 1500 bytes, ethernet + IP + TCP frame headers take quite amount of packet, reducing available bandwidth for data. Jongwoo Han 2019년 11월 28일 (목) 오전 3:44, Pinkesh Valdria 님이 작성: > Thanks A

Re: [lustre-discuss] zpool features, recordsize, post-upgrade?

Hi Marion, Enabling PFL and relocating file will double space consumption, so safe way is not to enable new features. Among other things, compression may be a good idea to try but remember it will increase OSS CPU utilization. Regards, Jongwoo Han On Tue, Oct 9, 2018 at 9:00 AM Marion Hakanson
