Hey guys,
I would like to ask for help with a Samba share in an HPC environment.
We have a pretty new HPC cluster that is running a proprietary software
that opens multiple Samba network connections. And these connections
perform intense reading and writing files.
At a given moment, I don't know if Samba or Windows has a network
unavailability error.
I would like to know if there is any configuration or tunning that can be
done in Samba to support these connections and these reading and writing
operations.
In the Samba log, there are no error messages.
Regarding the hardware, they are new machines, with less than 1 years of
manufacture and the storage of this HPC is a dedicated server. Specs:
HPE ProLiant DL380 Gen10
2x Intel(R) Xeon(R) Gold 5218 CPU @ 2.30GHz (total 64 cores)
192GB RAM
Centos 8.1
ulimit = unlimited
file system = XFS
smb.conf:
[global]
security = ads
workgroup = EXAMPLE
realm = EXAMPLE.COM
idmap config * : backend = tdb
idmap config * : range = 90000001-100000000
idmap config UNISIM : default = yes
idmap config UNISIM : backend = ad
idmap config UNISIM : schema_mode = rfc2307
idmap config UNISIM : range = 1000-90000000
idmap config UNISIM : unix_nss_info = yes
template homedir = /home/%U
template shell = /bin/bash
winbind use default domain = true
winbind refresh tickets = Yes
dedicated keytab file = /etc/krb5.keytab
kerberos method = secrets and keytab
vfs objects = acl_xattr
map acl inherit = Yes
store dos attributes = Yes
log level = 4
log file = /var/log/samba/log.%m
syslog = 0
syslog only = No
[scratch]
comment = Scratch area
browseable = yes
writeable = yes
path = /scratch
create mode = 0755
public = yes
read only = no
oplocks = no
level2 oplocks = no
Could someone help or give me any advice.
Thanks
